But there is a slightly difference between display($self) and $self->display(), when a class XY inherits from MyTest and implements it's own display() method. display($self) calls MyTest::display() even when invoked on an instance of XY, whereas $self->display() calls XY::display() when invoked on an instance of XY. So, one could say that display($self) breaks inheritance. This is often bad, but sometimes, it can be a useful trick.
