Re: [Haskell-cafe] some ideas for Haskell', from Python

You're probably right. I've played around with LISP macros a little, but it seems that most of the cases where you would use a macro in LISP you don't need one in haskell due to lazy evaluation. Although I haven't played around with them enough to say much one way or another.

Do you know of a particular example where a macro would be a big help in haskell?

Well, like many good programming tools, Lisp macros are another abstraction, but instead of dealing with data, they deal with code. They are a syntactic abstraction. They're often described as "programs that write programs." We all know how much Haskell likes abstractions ;)
