The Receiver as Arguments

A method is eventually invoked just like any other function. This means that the receiver just be passed as an argument. Traditionally, it is passed as the first argument.

This means a method call, such as 

aCardPile->addCard (currentCard)
Is translated into 
addCard (aCardPile, currentCard)
(This is ignoring the method lookup process, which we will discuss shortly).
