	This harness function is not necessary in the majority of cases in which it is used. Remove its usage to simplify tests and decrease the amount of domain-specific knowledge necessary to contribute to the test suite. Persist the harness function itself for use by future tests for ES2015 modules (such a helper is necessary for tests that are interpreted as module code).
