Consider that you want to test if an object supports a given method but don't want to check for NoSuchMethodError.

In this case you cannot point to a specify instance method (if you could, you could just have used an "is" test).

In the current @­MirrorsUsed this could be:

@MirrorsUsed(instanceMethods: 'foo')
import 'dart:mirrors';

We discovered this need in pkg/observe/test/path_observer_test.dart.

The package uses reflection to see if an object provides a specialized implementation of noSuchMethod.
