I am thinking of notions in addition to concurrency. Let me come up with a hypothetical list and repost. I worked on an "single login" project at Ford Motors and we implemnted an OS abstraction layer in C++ ( .. the collection of OS "functions" where defined in a C++ abstact class). Let me come up with a list of hypothetical functions to iluustrate my point.

Sure, that would be Concurrent Haskell:

If that's not what you're looking for, post again.
