Actually, I think the the impact of move semantics on performance of
well written existing code is minimal. On new code which uses more
types as values it's helpful.
Of course if the library were written today, it would all the new stuff.
I don't think it would be faster (unless it were made header only) but
it would likely have have half the number of lines of code (or less).
But the years long slog to address corner cases, workarounds for
compiler bugs and standard library bugs, etc. And there would be design
changes which would also create a bunch of ripple effects. So it would
really end up as a whole re-write.
