/**
 * @assertion A list literal <E>[elem_1 ... elem_n] is evaluated as follows:
 *
 * 2. For each entry in the map literal:
 *    i. If entry is a spread element:
 *       a. Evaluate the entry's expression to a value value.
 *       b. If entry is null-aware and value is [null], continue to the next
 *          entry in the literal.
 *       c. Evaluate [value.entries.iterator] to a value iterator.
 *       d. Loop:
 *          a. If [iterator.moveNext()] returns [false], exit the loop.
 *          b. Evaluate [iterator.current] to a value [newEntry].
 *          c. Call map[newEntry.key] = newEntry.value.
 *    ii. Else, entry has form [e1: e2]:
 *       a. Evaluate [e1] to a value key.
 *       b. Evaluate [e2] to a value value.
 *       c. Call map[key] = value.
 * @description Checks that final map is correct if two its elements have
