 I definitely didn't mean to get formal here, I simply meant a description of 
how to actually handle this, as it turns up now and then, and STL doesn't 
make this trivial.

 Oh, it's a map. Bugger. Ok, especially in that case it might be useful to 
point out that the solution is to use a temporary iterator for removal and 
advance the real one first. I can't be the only one who'd need a while to 
figure it out otherwise.
