/// @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 elements in a list literal are evaluated in order
