[Haskell-cafe] Refactoring status

[Emil Axelsson]

One approach to programming in Haskell, which I use all the time, is to write 
the type signature before the function body. This means that if I'm trying to do 
something strange, I will often be warned by the type checker even before I've 
written the strange code.

But I've also been bitten by the problem of having to change a lot of type 
signatures just because I want to e.g. show an overloaded variable.
