My conclusion is that it would only be nice to use with C++20 where one 
can use constinit to force a function to be computed at compilation 
time. Then we would be able to have:
  docstring const var = "sôme ascii text"_asc;

This would not compile. Forcing the use of constexpr is annoying IMO.

So shall we enforce these gcc/qt  versions?

Isn't it Python 3.8?

I know this feeling ;)
