Software Engineering discussion

This chapter is a lot more than just modules! The basic collection classes were interesting, along with some of the rules-based solutions in "Let's Find Some Cool Numbers" that reminded me a bit of Prolog. The Maybe type, along with the Just operator, were very new to me, and I don't recall seeing this concepts before in other languages.

May be it's too early to talk about this, but I am wondering if anyone here had an experience integrating Haskell with some other languages? As I understand from reading forums there are attemps to compile Haskell code into JVM bytecode. I also find discussions about challenges of integrating Haskell with .Net. C and C++ integration seems to be straightforward.
