Greetings:
When you invoke a method, the first argument to the method equal to the
method's invocant is automatically inserted.
i) Is this essentially the same as a C++ "this" pointer?
ii) Apparently, the first argument can be a reference to its object, or the
object.
iii) There is an example in the Camel book, in the Object-Oriented-Programming
Chapter (ch. 12), where accessor methods are being generated automatically; in
this example, it seems that the invocant is explicity placed into the first
argument. If you put in the this pointer, does PERL know not to put in another
one?
