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?

Yes, I'm aware of the interpreter. I'm not asking if you can dick around in the interpreter for a while then write your program for real. I'm asking about Haskell's support for interactive development.
