| /// by an argument list (that would turn it into a generic function invocation), |
| /// the meaning of e<typeArgs> depends on the expression e: |
| /// ... |
| /// - Otherwise the expression is a compile-time error. |
| /// This includes e having the static type dynamic or Function. We do not |
| /// support implicit or explicit instantiation of functions where we do not know |
| /// the number and bounds of the type parameters at compile-time. |
| /// It also includes e denoting a constructor. (We reserve this syntax for |
| /// denoting instantiation of generic constructors, should the language add |
| /// generic constructors in the future. Instead just write (C.name)<typeArgs> or |
| /// C<typeArgs>.name.) |
