Frozen

Another example of library doing very similar thing to what we want to do
is Frozen
<https://blog.quarkslab.com/frozen-an-header-only-constexpr-alternative-to-gperf-for-c14-users.html>.
For details you should consult the documentation,

but the general idea is similar: try to get good hashing based on the fact
the data is known at compilation time. Difference to us is that frozen does
perfect hashing.

"For details you should consult the documentation", right, we're getting
somewhere, oh, maybe not ... "Difference to us is that frozen does perfect
hashing": ... and your idea is ... to do imperfect hashing? The document is
far too long and there are far too many diversions/excursions into
la-la-land. Take as example the readme.md from frozen and put something
similar together, please.

Just stick it on github, that's what the rest of the world does ... if you
want to have it included in Boost, that's what you'll need to do in the end
anyway ...

... and put an appropriate license (BSL (
https://www.boost.org/users/license.html ) comes to mind, as that's what
you are proposing anyway) to deal with the above...
