/**
* @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 Iterable<Object> and S is not a subtype
* of Map<Object, Object>, then e is a set literal.
*
* @description Checks that if C is some subclass of Set<X>, then the literal is
* a set literal, but it is also a guaranteed type error even if the literal is
* a set but a wrong type
