What?

'this.foo()' is equivalent to 'foo()' - at least in all cases I can imagine
(and please educate me if there are cases where this isn't so!). It will
always call method 'foo()' either on the current class, or on the closest
superclass implementing the method.

There are cases where you might need an explicit 'this.' for referencing
instance variables (where you have a local variable of the same name,
shadowing the instance variable), but for method calls, 'this.' is always
superfluous.
