Re: Simple compiler question

Do any of the decent Haskell compilers allow you to just type function definitions at an interpreter prompt and use them in subsequent interactions, as you'd expect from a Lisp environment? I'm fed up of editing a tiny file separately and typing :reload each time, etc.

GHCi (part of GHC >= 5.00) allows you to use let to bind expressions at the prompt. E.g. you can do something like Prelude> let foo n = sum [1..n] Prelude> foo 1000 500500 which I agree with you is a very handy thing to be able to do. :-) Cheers, Chris.
