/**
* This formal parameter annotation indicates that the method searches for the given value, using
* reference equality ({@code ==}).
*
* Within the method, the formal parameter should be compared with {@code ==} rather than with
* {@code equals()}. However, any value may be passed to the method, and the Interning Checker does
* not verify that use of {@code ==} within the method is logically correct.
