Re: foo(foo) and foo(foo()) etc...

In the hope that it helps clarify further, Java is ONDS according to 
the labels I made up: The functions foo and the class variable foo are 
different things that happen to have the same name.

This example introduces overloading, in which the distinction between 
the two functions comes from its signature - this is another dimension 
that isn't covered by the four categories I suggested, but is orthogonal.
