Why does C++'s vector class call copy constructors? Why doesn't it just memcpy the underlying data? Wouldn't that be a lot faster, and remove half of the need for move semantics?

I can't imagine a use case where this would be worse, but then again, maybe it's just because I'm being quite unimaginative.
