<li>
Struct values are comparable if all their fields are comparable.
Two struct values are equal if their corresponding
non-<a href="#Blank_identifier">blank</a> fields are equal.
non-<a href="#Blank_identifier">blank</a> field values are equal.
The fields are compared in source order, and comparison stops as
soon as two field values differ (or all fields have been compared).
</li>
<li>
Array values are comparable if values of the array element type are comparable.
Two array values are equal if their corresponding elements are equal.
Two array values are equal if their corresponding element values are equal.
The elements are compared in ascending index order, and comparison stops
as soon as two element values differ (or all elements have been compared).
