Care to save me the effort of looking it up and tell me what Data.Map does that Python's dict doesn't? I guess if it is functional then every mutation must copy and return a new data structure? (Which will be much more efficient in Haskell than in Python - Haskell can share most of the underlying data whereas Python would have to create a new dict every time. At least it only stores references.) Michael Foord -- http://www.ironpythoninaction.com/ -- http://mail.python.org/mailman/listinfo/python-list
