Thank you for the contribution!

Answering my own question: I guess, it may be useful for methods of template classes and for template methods, where the template declaration doesn't make it clear whether the method is overridden or not. However the author may want the compiler to ensure the instantiation actually overrides something.

nit: `It should look up ...` sounds like a requirement, however, you exactly know what the implementation does, so `It looks up ... or updates ...` is better. Maybe even `Results are memoized in PossibleMap.`

Same below.
