Sounds good.

I'm also undecided:
- On the one hand, requiring that explicit specification of allocator
type whose value_type matches the desired value_type is nice.
- On the other, it's a little repetitive: we already specify
value_type in the parameter list, and every allocator type provides a
mechanism to rebind for a given value_type. It may also feel a little
inconsistent: e.g. with Clang/libc++ the above example with
std::vector static_asserts, yet { std::list<int, std::allocator<void>
> l; l.push_back(1); } will compile fine.

Benchmarks comparing against std::vector would be nice to have
(whenever you have time).

Best,
