Hello,

for my diploma thesis, I need to find information about integration of functional and imperative programming concepts. Could somebody of you point me to good websites, papers, etc. about this topic?

"Tackling the Awkward Squad" and "State in Haskell" both probably on Simon Peyton Jones's webpage, are good places to start; track back their references. You'll probably end up with Moggi, and Wadler's popular introductions to Moggi. That's all the monad approach; for other approaches you could look at ML and all the fun they had with polymorphism and references, or you could look at Lisp/Scheme and see what they do ("Structure and Interpretation of Computer Programs" is a classic textbook here, introducing functional, imperative, and object paradigms, all in the same language (Scheme)).
