For this specific use, it doesn't need to. It can just match against a StringLike concept, as I said.

Except that you can't use concepts in a compiled library, only in a header-only one. (Or it still requires you to write that concrete type conversion.)

Of course you can. class string_view { public: template > string_view( StringLike const& sl ): p_( sl.data() ), n_( sl.size() ) {} }; void my_compiled_library( string_view sv ); This is not something theoretical. E.g. Victor Zverovich has independently come to the same conclusion: https://twitter.com/vzverovich/status/1333111364357746690
