An IDE would help with this, at least for a strongly typed language ('go to definition'). For something like Perl, good luck! My other complaint is when the base class is updated independently of the child class. Suddenly your code is breaking because a new field is being set in the original function but not your override. For that reason I tend to inherit to extend only, as much as possible. I prefer to write a wrapper if it's a neater solution.
