You are wrong. Perl will search up the inheritance tree for class methods. The only time it will only look in a single package is using the syntax $foo->Bar::baz() or Foo->Bar::baz(), which will pass a $self of $foo or "Foo", respectively, but invoke the method in the Bar package.

You are also wrong about import(); it is the entire point of OO not to have to sully someone else's namespace with your own symbols.

You would also have easily found out that your assumption is wrong in this case if you had cared to look at the Class::Factory source - no import() function is defined nor is any exporter used.

Makeshifts last the longest.
