I am trying to put together a nice priority queue package.
With the new ops, I feel I should standardize my code to use a single
test, rather than willy-nilly use < and <= in various places.
What opinions do others have on whether I should use "<" or "<="?
I realize exceptions may get thrown or strange orders result from
using non-total-ordering relations (I view as a user problem).

So here's my question:
I'm building these priority queues on either < (>) or <= (>=).  If you
were to build only one of these two on a type which would it be?
Which of the two would you expect to be used in such a package?
How should I make this choice?
