Yes, Howard's (exquisite in my opinion) library is specifically for
C++, and is moving forward
for inclusion in the ISO standard. (Indeed, a subgroup gave it
unanimous consent just this
morning.)
>From http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0355r4.html:
"The implementation has been ported to Windows, Linux, Android,
macOS and iOS."
I've BCCd Howard in case he has anything more to say about it (although
I wouldn't be surprised if he already follows this list anyway).
