in thread inheritance turns back and bites

Always use SUPER instead of the parent-class-name; so in the case of changeing the parent-class, you won't have to replace all the "SomeData::" stuff to the new parent-class-name.
SUPER is pretty super.

    But SUPER is wrong here, I like to use SomeData or build something with __PACKAGE__.
      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.
