Everywhere I go, the standard library has been a chronic case of
Procustes meets Godzilla.

Sadly, the same is true for most of boost as well. When it was new, I
encountered an ABA problem with boost mutex on Windows - (lazy event handle
init). I ended up writing one anyway.

It isn't a case of reinventing the wheel, so much as it is making one that
is at first round.

Interpolated literals can be made simple, but honestly the complexity
introduced in the compiler may well exceed what it removes from the average
codebase.
I see it being beneficial where an application has a lot of text baked into
it, but that isn't what I usually encounter (localized strings are
generally mapped to IDs, which can't be formatted strings). I'm a sucker
for syntactical sugar where it can be afforded, though.
