But less than half as much I and others would use :-) e.g. your hxarray is
not exception-safe, has no emplace_back, has no integration with ranges
(insert_range, assign_range etc.), and so on. Of course you can make
something that compiles faster if you just design something for your
specific needs. That shouldn't be surprising to anybody.

Yes, all those features in std::vector and the rest of the library have a
cost, but IMHO they're worth waiting for 50ms instead of 16ms.
