compilation fails with 'no enclosing instance' error

[Alex Buckley]

Regression. MyImpl inherits the instance method foo(Object) from Impl, 
and foo(o) should invoke the inherited method. At least javac is 
recognizing that the type Impl is an important source of truth.

The foo(Object) method in base.BaseImpl is irrelevant because, having 
package access, it's not inherited by Impl.
