same way as regular methods as far as overriding is concerned ("override"
is now allowed, and even required, to override them in a descendent class;
and similarly, "reintroduce" must be used if a category wants to replace
a method in a child class if that method was added by another category in
a parent class)
* print the name of owning objcclass/category of the original method in case
override/reintroduce is missing for objc methods, since this is no longer
always the parent class
