Using std::string as a dynamically-resizable buffer of bytes isn't completely
unreasonable, although I can't see many reasons to prefer std::string to
std::vector for that purpose.
For either type, it

The possibility of storing something other than char in std::string never
entered my mind, and I'm pretty sure the container was never meant for that.
But whether the standard has all the restrictions in

As a baseline, I think it would be great to get std::string to enjoy the same
benefits as other containers WRT aliasing. Going a step further, I'd expect
users of all containers to benefit from the aliasing

It has never been very clear to me what restrict means on a struct member, but
I believe adding it to the pointer in vector means that in a function:
void f(vector*a, vector*b)
the compiler could assume that
