Detailed Description

Models the abbreviated syntax to constrain a template type parameter: template <convertible_to<string> T> void print(T object); ~~~~~~~~~~~~~~~~~~~~~~ Semantically, this adds an "immediately-declared constraint" with extra arg: requires convertible_to<T, string>

In the C++ grammar, a type-constraint is also used for auto types: convertible_to<string> auto X = ...; We do not model these as TypeConstraints, but AutoType(Loc) directly.
