Maybe it could also catch errors in my cafe emails...
sqrs l = map sqr l where sqr x = x*x

Thanks for the pointers, but I think I'm looking for type information specific to my program. The VisualHaskell feature of which I am envious is the ability to tell me the type of any identifier in my program. Disclaimer: I've never used VisualHaskell and am going only by what I read on its features page. > sqrs l = map fn l > where fn x = x+2 Presumably, VisualHaskell would let me mouse-over/select the x in x+2 and tell me that it's of type 'Num a => a'; where I could mouse-over/select srqs and it would tell me that it's of type 'Num a => [a] -> [a]' (not necessarily the same a!). Of course this isn't too helpful with this example, but start imagining method definitions for >>= or the like on hairier data structures. I don't know how VisualHaskell handles type-errors, but I think it'd be neat if it gave me as much info as possible when errors were in the picture--that's exactly when I need the info the most! And, of course, I'd like this functionality in a multi-platform editor.
