:mrdocs:

This component‐private trivial tag type is used to distinguish between arguments passed by a user, and an `enable_if` argument. It is not default constructible so the following construction never invokes a constrained single parameter constructor: ` struct SomeType { SomeType(int, const std::string &s = "default"){} };
