I have not yet needed a priority queue for any application, so I have  
no specific technical opinion in this particular proposal.

I would suggest that if you continue to receive relative silence on  
the topic, then it may not be a good candidate for the standard  
"containers" library, simply because a demand for it has not yet been  
demonstrated.  (You can easily release it as a separate package anyway.)

This, I hope, will be sufficient of a cue for anyone who _does_ care  
about PQs to speak up now!
