\ as λ in haskell

[scarf005]

lambdas are written as \ in haskell. ex) \x y -> x + y is same as lambda x, y = x + y in python.
it'd be a nice addition for haskell to render it as λ, say λ x y -> x + y

You want to replace any backslash to lambda? Aren’t backslashes used for anything else in Haskell?

[scarf005]

yeah, found out it'd be impossible to distinguish between \ with parameter (\x -> x) and function name starting with \ (\)
. also \n and \ in strings. it'd impossible to distinguish them within bounds of ligatures.

could you close the discussion as finished/wontfix?
