Because he's working with objects and wants to replace the contents of 
the current object with another one: no (it could be designated "const" 
for better performance maybe). Remember, in an object (as opposed to a 
class instance), self is not a pointer but the object itself. So he's 
just overwriting the contents of the object with some other contents. I 
agree it's ugly, but it won't create a memory leak.
