| /// @assertion A list literal <E>[elem_1 ... elem_n] is evaluated as follows: |
| /// |
| /// 2. For each element in the list literal: |
| /// i. Evaluate the element's expression to a value value. |
| /// ii. If element is a spread element: |
| /// a. If element is null-aware and value is [null], continue to the next |
| /// element in the literal. |
| /// b. Evaluate [value.iterator] to a [value] iterator. |
| /// c. Loop: |
| /// a. If [iterator.moveNext()] returns [false], exit the loop. |
| /// b. Evaluate [iterator.current] and append the result to list. |
