it is very much like the C "this" pointer. actually, the
name isn't special in anyway, you could use "this" if you
wanted, but i've yet to see any code that uses something
besides "self".

unlike C, you _must_ use this self variable when referencing
members and methods for the class.

this "self" is always the first argument passed to any
method functions of a class. when you "forget" to include
it in the method argument list, you'll quickly get
"wrong number of argument" errors when you try to call
the method.
