[new release] melange (5.0.0-53)

CHANGES:

- Make the `unprocessed` alert fatal by default
  ([melange-re/melange#1135](melange-re/melange#1135))
- support `-H` for hidden include dirs in OCaml 5.2
  ([melange-re/melange#1137](melange-re/melange#1137))
- support `[@mel.*]` attributes in uncurried externals
  ([melange-re/melange#1140](melange-re/melange#1140))
- add Worker types to `melange.dom`
  ([melange-re/melange#1147](melange-re/melange#1147))
- Add support for dynamic `import()`
  ([melange-re/melange#1164](melange-re/melange#1164))
- Fix code generation of custom `true` / `false` constructors
  ([melange-re/melange#1175](melange-re/melange#1175))
- Fix code generation of OCaml objects that refers to an init variable in scope
  ([melange-re/melange#1183](melange-re/melange#1183))
- Support `[@mel.as "string"]` in variant definitions
  ([melange-re/melange#884](melange-re/melange#884))
- BREAKING: remove `[@@deriving jsConverter]` for variant definitions
  ([melange-re/melange#884](melange-re/melange#884)). Use `[@mel.as
  "string here"]` instead.
- Support OCaml 5.3 ([melange-re/melange#1168](melange-re/melange#1168))
- Upgrade Stdlib to the OCaml 5.3 Stdlib
  ([melange-re/melange#1182](melange-re/melange#1182))
- Support `[@mel.tag "the_tag"]` in variant definitions
  ([melange-re/melange#1189](melange-re/melange#1189))
  - combined with `[@mel.as ..]` in variant definitions and inline record
    payloads, Melange can now express types for discriminated union object
    shapes.
- melange-ppx: don't silence warning 20 (`ignored-extra-argument`) for
  `%mel.raw` application
  ([melange-re/melange#1166](melange-re/melange#1166)).
  - This change reverts the behavior introduced in
    ([melange-re/melange#915](melange-re/melange#915)).
  - The new recommendation is to annotate `%mel.raw` functions or disable
    warning 20 at the project level.
- ppx,core: propagate internal FFI information via attributes instead of adding
  marshalled data in the native primitive name
  ([melange-re/melange#1222](melange-re/melange#1222))
- melange-ppx: allow `@mel.unwrap` polyvariants not to have a payload
  ([melange-re/melange#1239](melange-re/melange#1239))
- `melange.node`: fix `Buffer.fromString` and add
  `Buffer.fromStringWithEncoding`
  ([melange-re/melange#1246](melange-re/melange#1246))
- `melange.node`: bind to all supported Node.js `Buffer` encodings in
  `Node.Buffer` ([melange-re/melange#1246](melange-re/melange#1246))
- `melange.js`: Add `Js.FormData` with bindings to the
  [FormData](https://developer.mozilla.org/en-US/docs/Web/API/FormData) API
  ([melange-re/melange#1153](melange-re/melange#1153),
  [melange-re/melange#1270](melange-re/melange#1270),
  [melange-re/melange#1281](melange-re/melange#1281)
- `melange.js`: Add `Js.Blob` and `Js.File` with bindings to the
  [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) and
  [File](https://developer.mozilla.org/en-US/docs/Web/API/File) APIs
  ([melange-re/melange#1218](melange-re/melange#1218))
- `melange.js`: add `TypedArray` types at the toplevel in the `Js` module
  ([melange-re/melange#1248](melange-re/melange#1248))
- BREAKING: remove `--mel-g`
  ([melange-re/melange#1234](melange-re/melange#1234))
- runtime(`melange.js`): port `[@mel.send.pipe]` functions to `[@mel.send]`,
  taking advantage of the `@mel.send` + labeled argument improvement (see
  above) ([melange-re/melange#1260](melange-re/melange#1260),
  [melange-re/melange#1264](melange-re/melange#1264),
  [melange-re/melange#1265](melange-re/melange#1265),
  [melange-re/melange#1266](melange-re/melange#1266),
  [melange-re/melange#1280](melange-re/melange#1280),
  [melange-re/melange#1278](melange-re/melange#1278))
- core: fix a crash related to finding constructor names in pattern matching triggered by dune's earlier implementation of `(implicit_transitive_deps false)`
  ([melange-re/melange#1238](melange-re/melange#1238),
  [melange-re/melange#1262](melange-re/melange#1262))
- core: pre-compute the closure param map for functions inlined with
  `--mel-cross-module-opt`
  ([melange-re/melange#1219](melange-re/melange#1219))
- BREAKING: ppx: print the `deprecated` alert for `@@deriving abstract` at the
  declaration site rather than at (all) usages
  ([melange-re/melange#1269](melange-re/melange#1269))
- JS generation: prettify `for` loops
  ([melange-re/melange#1275](melange-re/melange#1275))
- JS generation: improve formatting for `throw` and `return` statements, JS
  objects ([melange-re/melange#1286](melange-re/melange#1286),
  [melange-re/melange#1289](melange-re/melange#1289))
- JS generation: improve formatting for empty return and continue statements
  ([melange-re/melange#1288](melange-re/melange#1288))
- JS generation: remove trailing spaces before commas in `export`
  ([melange-re/melange#1287](melange-re/melange#1287))
- JS generation: remove redundant switch cases branches
  ([melange-re/melange#1295](melange-re/melange#1295))
- JS generation: move space before comma inside `for` definition
  ([melange-re/melange#1296](melange-re/melange#1296))
- JS generation: add space before while loop condition
  ([melange-re/melange#1297](melange-re/melange#1297))
- JS generation: improve indentation of parenthesized blocks
  ([melange-re/melange#1293](melange-re/melange#1293))
- JS generation: add space after constructor comments
  ([melange-re/melange#1294](melange-re/melange#1294))
- JS generation: improve identation of `switch` cases
  ([melange-re/melange#1299](melange-re/melange#1299))
- JS generation: don't generate empty `default:` cases in `switch`
  ([melange-re/melange#1300](melange-re/melange#1300))
- JS generation: emit `module.exports` in CommonJS instead of `exports.x`
  ([melange-re/melange#1314](melange-re/melange#1314))
- JS generation: remove trailing newline after `switch`
  ([melange-re/melange#1313](melange-re/melange#1313))
- ffi: allow annotating `@mel.send` FFI with `@mel.this` to specify which
  parameter should represent the "self" argument.
  ([melange-re/melange#1303](melange-re/melange#1285),
  [melange-re/melange#1310](melange-re/melange#1310))
  - This improvement to the FFI allows expressing more FFI constructs via
    labeled and optionally labeled arguments, e.g. `external foo: value:string
    -> (t [@mel.this]) -> unit = "foo" [@@mel.send]` will now produce
    `t.foo(value)` instead of `value.foo(t)`.
  - It also allows removing usages of `[@mel.send.pipe: t]` in favor of
    `[@mel.send]` with `[@mel.this]`, including when used with `@mel.variadic`.
- ppx: deprecate `[@mel.send.pipe]`
  ([melange-re/melange#1321](melange-re/melange#1321))
- core: fix missed optimization on OCaml versions 5.2 and above, caused by
  [ocaml/ocaml#12236](ocaml/ocaml#12236) generating
  multiple function nodes for `fun a -> fun b -> ...` in the Lambda IR.
