I do not want to supply the whole interface of vector.
Why not?
It's a lot of work, so if rather have a reason to do this. And in general it is not a drop-in replacement for vector, so there is no reason to pretend it is.
For the operations that they have in common, it is almost a drop-in replacement. I say almost, because this class is really about speed, and often don't allow overlapping ranges, assignment to *this etc. The exception-safety guarantees might also be weaker if it hurts performance.
I think anything that's an "almost" needs an explicit rationale. I really don't, for example, see why the self-assignment check is worth omitting.
The rationale would be simplicity, speed and less generated code. -Thorsten
