| // "Identifier Reference": |
| // |
| // "A built-in identifier is one of the identifiers produced by the |
| // production BUILT_IN_IDENTIFIER. It is a compile-time error if a |
| // built-in identifier is used as the declared name of a prefix, class, |
| // type parameter or type alias. It is a compile-time error to use a |
| // built-in identifier other than dynamic in a type annotation or type |
| // parameter." |
| // |
| // Observation: it is illegal to use a built-in identifier other than |
| // `dynamic` in a type annotation. A type annotation is not fully defined |
| // in the specification, so we assume this means that the grammar |
| // production "type" cannot be a built-in identifier, and it cannot contain |
| // a built-in identifier at a location where it must denote a type. |
| // |
| // Note that we have several ways to use built-in identifiers other than |
| // `dynamic` in other locations in a type, e.g., `Function(int set)`. |
