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?

you can't hack on a normal, compiled, running program
What does this mean? You do know that compiled Haskell programs are executable binary programs. This is like asking if you can hack on a compiled C program while it's running: it's possible if that's what you really want.
