STL container function return values

Question

When looking over the member functions of the STL containers, an odd thought occurred to me. Why don\'t functions like std::vector::push_back(T) not ha

Answer 1

Maybe because it was not "needed"?

erase() and insert() have no other way than return an iterator to allow continuing a loop it was called in.

I don't see a good reason to support the same logic with push_back().

But sure, it would be be wonderful to make more cryptic expressions. (I don't see an improvement in your example, it looks like a good way to slow your coworkers when reading your code...)
