 * @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 e has no typeArguments, no useful context type, and no elements, then e is
 * treated as a map literal with unknown static type. In other words, an
 * empty {} is a map unless we have a context that indicates otherwise
