libfmt 10.2 / gcc 13
I have a string-like class implicitly-convertible to std::string_view. Based on older documentation I'd expect that to Just Work in fmt::format()but I see from other issues that matching on implicit conversion has been disabled. Annoying, but fair enough.
When I create a fmt::formatter specialisation for my class that simply inherits fmt::formatter<string_view>, this does not work, fmt::format still considers S to be an un-formattable type.
template<>
class fmt::formatter<S>
: public fmt::formatter<std::string_view> {};

The equivalent code using std::formatter works ok: https://godbolt.org/z/T7zzKzzf3
