/// If the type alias is not instantiated, then it's a function from types to
/// types, not an alias for a single type, and tearing off a constructor works
/// equivalently to tearing off a corresponding generic function where the
/// generics match the type alias, not the underlying class. The result is a
/// compile-time constant.
///
/// @description Checks that the result of the not instantiated type alias
/// tearing off is a compile-time constant.
