I originally posted this in comp.lang.c++ (and latterly in
comp.lang.c++.moderated)  but got almost no response. Now trying here.

<question>

Earlier on today Stuart Golodetz posted here a question regarding clearing
an STL priority queue. My first mental  response was "Well, just call
clear!" but  a quick flick through Josuttis told me that
std::priority_queue, and the rest of the collection adaptors (stack et al)
don't support this method.

A couple of  people then posted as solutions my next idea - assign an empty
adaptor object to the one you are trying to clear. Obviously, this will work
but ... why don't stack, priority_queue et al. support a clear() method? Why
should not _all_ STL collections support the same "remove everything"
method? I can see no obvious reasons - your thoughts?

</question>
