I was looking for a good pairing_heap implementation and came across one that had apparently been checked in a couple years ago (!).
Have you looked at the heapq module? What application do you have for a pairing heap that you can't do readily with the heapq module?
Anyway, the immediate author of this code is Dan Stutzbach (as Raymond Hettinger's checkin message says); you probably should contact him to find out whether the project is still alive.
