That depends on the container. std::vector<> might invalidate
references, std::deque might (but not on insertions at either end),
and std::list, std::[multi]map and std::[multi]set never do.

If I have a reference to an object that's sitting in some STL collection
(not a pointer collection but the actual objects), and then the collection
is resized (potentially moving the objects), is my reference still good? I
know that iterators become undefined at this point but I'm fuzzy on what
happens to a reference. Thanks.
