Hint: Don't put signatures on functions, then. Instead, let the compiler infer the type for you! If you want to know what the type is, ask GHCi with :info. And if you think it is helpful documentation, you can copy-paste the correct signature from ghci into your source code!
There should always be signatures.
I do almost unrestrictedly agree!
Deciphering code without type signatures is -- except in fairly trivial cases -- always a nuisance, and if the author chose short names instead of telling ones, it is positively disgusting!
That's not really what I meant. I meant that, especially when you are figuring out a new language, getting the types inferred for you is helpful and also instructive... I wasn't suggesting that they be left out permanently. Jules
