Description
(as of Coq 8.8)
FSet has a min_elt function to query the smallest element, but there is no counterpart for that in FMap, which would make it convenient to turn it into a priority queue.
Alternatively, is there a released and maintained implementation of priority queues in Coq?
Some meta-questions:
- Is this the place for stdlib feature requests?
- Are the stdlib2 efforts advanced enough that we should focus efforts over there instead of improving the stdlib?

Research direction
Start by reading the existing FSet.min_elt operation and the FMap API to determine the expected counterpart and ordering behavior. Check whether the priority-queue alternative or stdlib2 questions affect the scope; done means providing a documented FMap.min_elt operation with coverage for its behavior.
