I've been using the Rogue Wave implementation of the STL that comes with
Borland C++ 5.01.  According to the Rogue Wave Standard C++ Library
User's Guide and Tutorial the insertion or removal of values from a set
does not invalidate iterators or references to other elements in the
collection.
I can't spot this in the (2nd December 1996) draft standard anywhere, is
this behaviour defined in the draft?
Same question again for the iterator representing the end of a set, only
stronger: are there any operations that can be performed on the set that
will invalidate a stored iterator represent the end of the set?  (FWIW,
RW's std::set<T>::swap function swaps the iterators that end returns,
but I couldn't spot anything else which looked like it would change it.)

Thanks,

Richard.
