[Haskell-beginners] Compiling shared (dll) library

Aaaaaaaaaaa!
You are the Great Magician!

 Sorry for a stupid question, how is it?

And one more question, please: how I can export genexPure :: [String] ->
[String] to achieve all preferences of lazy list? Not all array at once,
but to get someting like an iterator, what I can call to get new genex.

Thanks a lot,
