Thanks for the links and valuable info!

I already played before with Scott Schurr's implementation but wasn't 
able to do with it everything I wanted (see below).

Do you know about some example where this is actually done? I can't see 
a straightforward way to pass such constexpr string as a template 
parameter and do something reasonable with it internally. In particular 
to generate a C++ type from a string literal. I think this is the most 
important concept. Correct me if I'm wrong but it seems to me that if 
you're dealing with constexpr strings you must handle them in constexpr 
functions and AFAIU that's not what Abel wanted. The technique proposed 
by TONGARI allows to generate types, at least in some cases, still not 
in Abel's case. Or am I missing something?
