This thread has languished a bit on the list, so I picked it up.  I've tried it out on my local systems (greenfly, unicorn, icarus, macOS, and a Fedora x86_64 laptop I use as my daily driver) using clang, gcc, and MSVC.  It seems to work, I still need to measure performance.

We currently require MSVC 2019, so before this could be accepted, this 
requirement would need to be adjusted (including documentation, 
buildfarm updates, etc.).  Maybe a bit late for that.
