in thread inheritance turns back and bites

If your intent is to ensure that increment calls add in the same package, why not use:
sub increment { my $self = shift; &add($self, number => 1); }
Use subroutine calls when you want to create your own explicit binding, use -> notation when you desire runtime binding of the message.

Of course, it would be my opinion that it is particularly bad form for a child class to re-implement a method in a manner that is not backward compatible - it's a violation of the contract as far as I'm concerned.
