should python have a sort list-map object in the std-lib?

ahh, i hadn't thought of using a proirity queue but that is the correct
solution most of the time, except i suppose when you have input that
causes you to excessively reheap which could be problematic.

i may still look into writing a general sorted map though, it could be
useful especially if there were and easy way to set the type of
functionality required with out resorting to several different types of
sorted-maps.
