| * @assertion Finally, we define inference on a setOrMapLiteral collection as |
| * follows: |
| * |
| * If collection is unambiguously a set literal: |
| * |
| * If P is ? then the static type of collection is Set<T> where T is the least |
| * upper bound of the inferred set element types of the elements. |
