Does not compile with -Werror option, cause of some macro problem

[NotZahar]

gcc 13 gives the following:

../lexy/lexy/dsl/punctuator.hpp:15:26: error: unnecessary parentheses in declaration of ‘period’ [-Werror=parentheses]

May be this line (from punctuator.hpp:15):

inline constexpr auto(Name) = _##Name {}

Should be replaced by:

inline constexpr auto Name = _##Name {}

Hm, I think then I had a warning about macro arguments not being parenthesized :D Can you do a PR with the fix and see what the CI system says? Thanks.
