I think somebody owes me money…

That’s why I commonly wrap sequences in Python with the enumerate function. It maps every element in the sequence with a tuple containing (index, value).

That comprehension lists aren’t a superset & always better than map (which I recall something about Guido saying, once upon a time)?

It’s really good to see the beaty of haskell even when not coding myself! I completely agree with you. I think a major advantage of Haskell over other languages is composability (except for when you’re in a Monad, ofcourse). It might be interesting to note that map, for example is really easy to make multi-threaded (the compiler could even automatically do that), whereas a compiler in a language with for-loops and side-effects is not able to make that decision. I think Haskell’s going to win big time on the ease of making applications run on multiple cores and/or processerors.
