- needs to use async* to declare async generator methods.
- Needs to use yield* if delegating yield semantics are intended.
- Has assignment to private name method, which is not allowed and throws a TypeError at runtime.
- handle multiple $DONE calls
- fix calls to private methods

class-fields-public doesn't apply to all tests that are generated from these templates

Class Fields: convert propname-error into non-generated to avoid creating erroneous tests where restrictions do not align.
