/**
 * @assertion A runtime list literal <E>[e1... en] is evaluated as follows:
 * • First, the expressions e1... en are evaluated in order, they appear in the
 *   program, yielding objects o1... on.
 * • A fresh instance a, of size n, whose class implements the built-in class
 *   List<E> is allocated.
 * • The operator []= is invoked on a with first argument i and second argument
 *   oi+1, 0 <= i < n.
 * • The result of the evaluation is a.
 * @description Checks that ith element is set to o(i+1), o <= i < n.
