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> {}; ``` https://godbolt.org/z/aMqqWaso9 The equivalent code using std::formatter works ok: https://godbolt.org/z/T7zzKzzf3
