I too am unsure why you feel the need to detect / prevent this. But the first technique for doing that which pops into my head has not been mentioned yet: 

sub Foo::bar { croak "bar() only meant for use from base class" }

or thereabouts. Of course, you've taken all of the meaning out of your class and method names so it is hard to "get" what your point is in such an abstract case.
