 * @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
 * with all wrapping FutureOrs removed), and Cbase is not ?, then let S be the
 * greatest closure.
 * ...
 * if S is defined and is a subtype of Map<Object, Object> and S is not a
