I think it is the wrong approach to suggest changing all the modules that do this. It also fails to solve the larger problem, which is when class A inherits from class B, but B contains a private utility subroutine that you don't want to inherit.

People have been talking for a long time about a :method attribute for subroutines. If there were such an attribute, you could simply have a rule that says that only :method subroutines could be inherited. Then the right fix would be very simple: Just tag Exporter::import with the :method attribute.
