| * @assertion A runtime map literal <K, V>{k1: e1...kn: en} is evaluated as |
| * follows: |
| * • First, the expression ki is evaluated yielding object ui, the ei is |
| * evaluated yielding object oi, for i ∈ 1..n in left to right order, yielding |
| * objects u1; o1 ... un; on. |
| * • A fresh instance m whose class implements the built-in class Map<K, V> is |
| * allocated. |
| * • The operator []= is invoked on m with first argument ui and second argument |
| * oi, i ∈ 1..n. |
| * • The result of the evaluation is m. |
| * @description Checks that a fresh instance is allocated when evaluating a |
| * runtime map literal. |
