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.
