Hi,
I use the newest CTRE 3.7.2 (but also tried a 2.x version with same results) and MSVC2022.

With C++17 activated, I can compile the examples, with C++20 activated, I get a compile error.

'ctll::fixed_string ctll::fixed_string(ctll::fixed_string)': could not deduce template argument for 'ctll::fixed_string' from 'const ctve::pattern<11>'

The problem seems to be, that you cannot construct a ctll::fixed_string out of a ctve::pattern or the underlying ctve::basic_string, as there is no constructor for std::array<char> in ctll::fixed_string.

I could not figure out, why it compiles in c++17. I guess some option is set in this mode, but I do not know which one.
