| * @assertion The grammar changes for map and set are a little more complex |

| * The changed and new rules are: |
| * |
| * setOrMapLiteral: |
| * mapLiteral | |
| * setLiteral | |
| * mapOrSetLiteral |
| * ; |
| * |
| * mapLiteral: |
| * const? typeArguments? '{' mapLiteralEntryList? '}' |
| * ; |
| * |
| * mapLiteralEntryList: |
| * mapLiteralEntry ( ',' mapLiteralEntry )* ','? |
| * ; |
| * |
| * mapLiteralEntry: |
| * expression ':' expression | |
| * spread |
| * ; |
| * |
| * setLiteral: |
| * 'const'? typeArguments? '{' spreadableList '}' ; |
| * |
| * mapOrSetLiteral: |
| * 'const'? '{' spread (',' spread)* '}' ; |
| * |
| * @description Checks the very simple cases where some values are combined with |
| * the existing set or list of integers |
