Nice, but this counts the characters at compile-time:

std::string_view sv( "Hello World!" );

But sizeof(string_literal) includes the null-terminating character.

 Gosh! Maybe you could do sizeof()-1 then. Just a thought!
 

How about this:
template<size_t N>
consteval size_t xstrlen( char const (&x)[N] )
{
return N - !x[N - 1];
}
