To be clear, I'm looking for an opportunity to expand my horizons. Other than return type covariance, or when you need to distinguish between the subclass supplying a 0/nil/""/false return value and there not being an event handler, I can't think of a reason to use method overriding.
I would genuinely love to know when you think method overriding best suits the problem at hand.
