Assuming I'm in control of how many elements my vector has allocated through reserve(), is it safe to keep my current iterators to existing elements in between calls to insert() and erase() as long as the vector doesn't need to reallocate?

Note 3:
[3] Warning: there is no guarantee that a valid iterator on a is still valid after an insertion or an erasure
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
