| * @assertion an extension declaration is a top-level declaration with a grammar |
| * similar to: |
| * <extension> ::= |
| * `extension' <identifier>? <typeParameters>? `on' <type> `?'? `{' |
| * memberDeclaration* |
| * `}' |
| * Such a declaration introduces its name (the identifier) into the surrounding |
| * scope. The name does not denote a type, but it can be used to denote the |
| * extension itself in various places. The name can be hidden or shown in import |
| * or export declarations. |
| * |
| * @description Check that the name can be hidden or shown in import or export |
| * declarations. |
