Detailed Description

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:

       optional<SomeType> o(int, {});

See Component bslstl_optional
