This is a feature request to add weak_use_count() to weak_ptr.
I am not interested in this feature for anything else than a debugging
aid. Recently, a weakness was highlighted in one of my projects, I had
stale weak_ptr objects that would remain in core even if all copies of
weak and shared pointer objects should have been eliminated by now.
To confirm the bug fix and audit the rest of the code base, a debugger
was used to set a conditional break point on internal members of
weak_ptr. I would rather have the ability to write assertions when
needed hence weak_use_count().
