/**
 * @assertion The grammar changes for map and set are a little more complex
 * because of the potential ambiguity of collections containing only spreads.
 * 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 that exception is thrown if spreadable element is not
 * Iterable for spreadable set.
