macros, metaprogramming,etc

hi!
I'm a smug lisp weenie. One of the things I like the most of lisp is macros, because it's a huge, important abstraction. With macros the lack of syntax stops being a burden and starts being an advantage.
Still, lisp is not the only language with macros. I've seen languages like Haskell, OCaml, Nemerle, TCL, and maybe Joy (to tell you the truth I can barely read Joy code).
Do you have any experiences in this stuff? is it as powerful and easy to use as in lisp?

Lisp macros are basically just lazily evaluated functions. Presumably Haskell should be able to do the same stuff.
