I was looking at this again in the context of

If we ever wanted to make the debug mode iterators SCARY (or if the standard
ever required it) then I think we would

As for solving the problem of switching containers, use a typedef for the
container, or

It's not an option IMHO. See http://www.stroustrup.com/SCARY.pdf for the
benefits of the current design. Those benefits outweigh the advantage of having
non-portable code diagnosed. Debug iterators can't b

I agree that anyone depending on map and multimap iterators to mix deserves
whatever happens as a result. It would, however, be nice g++ would reject such
programs outright. Currently this is accepted:

The standard allows iterators of different containers to be different, your
program is not portable of it assumes they will (or will not) be the same type.
I don't consider this a bug, and am not very moti

A similar divergence of types occurs between the types
