 * @assertion Let e be a setOrMapLiteral.
 * If e has a context C, and the base type of C is Cbase (that is, Cbase is C

 * greatest closure.
 * ...
 * if S is defined and is a subtype of Iterable<Object> and S is not a subtype
 * of Map<Object, Object>, then e is a set literal.

 * a set literal, but it is also a guaranteed type error even if the literal is
 * a set but a wrong type
