----------------
IMO, most functions with unnamed parameters will be derived from some base method. Otherwise, why would they have an unnamed parameter (yes, there are cases, but not that many)?

To this end:
- Add tests for methods overriding methods with named parameters.
- I think the common pattern for the unnamed parameter comment is /*<parameter name>*/ Could we extract the parameter name from the overridden function.
