struct/enum fields names

[sdancer]

can't mix underscores or other symbols to names, how to define a large protocol ?

imagine a few hundreds of these used on real code to implement a network protocol:

pub type OptionType {
  OptionTypeFoo
  OptionTypeBar
  OptionTypeBaz
}
pub type ExampleResponseOrError {
  ExampleResponseOrErrorResponse(response: option.Option(Response))
  ExampleResponseOrErrorError(error: String)
}

in other langs, u at least can use some symbols on the names

pub type OptionType {
  OptionType_Foo
  OptionType_Bar
  OptionType_Baz
}

in rust u have multiple alternatives to avoid name clashes, and reduce visual clutter or at least hint where a name ends and another stars

This is something I do often in Elm. Being able to use underscores in names is very useful to make the namespaces of custom types clear.

However, would be even better being able to write this like Rust e.g. ExampleResponseOrError::Response.

@sporto of course, rust-like would be ideal, but i guess it might require more complex rework on the compiler
