What about let bindings and let-in clauses?

[jubobs]

The style guide has recommendations for where bindings. What about let-in clauses?

In my opinion, the recommendation for if-then-else clauses,

Short cases should usually be put on a single line (when line length allows it).

also applies here. For longer let-in clauses, I favour the following style,

searchSpace d =
  let
    m = 10 ^ d - 1
    n = 10 ^ (d - 1)
  in
    [x * y | x <- [m, m - 1 .. n]
           , y <- [m, m - 1 .. x]]

i.e. Indent the let and in keyword two spaces to set them apart from the rest of the code and indent the definitions in a let clause and the body of an in clause 2 spaces. This is consistent with the style guidelines for where bindings.

Thoughts?
