Haskell Development

Hey /prog/, tell me things about Haskell.

How is Haskell's support for the type of interactive development that I, as a Lisper, demand? Sometimes I look at Haskell for a while but it has all kinds of syntax and I've gotten the impression that developing in Haskell requires a step backwards to batch compilation, so I give it a rest pretty quickly.

Could some nomads either confirm or disabuse me of my notions?

FUN FACT: Haskell used to be strictly an interpreted language.

It's very common to load a file into GHCi (with :load or :module +) and play around with the functions. That includes writing off-the-cuff tests for them. You'll see people doing this on IRC every so often if you lurk in #haskell, too.
