OK... I get it... I understood your argument (although
ya cleared up a few other things), but I still just
didn't GET why you couldn't do a '++' method that
simply did something like 'self = self.succ'

Of course, after actually TRYING that on my own (the
best learning tool ;), I find that I can't modify
self.  I guess that makes sense.  

And I assume Ruby doesn't want to go the way of C# and
have safe vs. unsafe data, right?  How bad would it be
to have a an 'unsafe' object that COULD modify self?

Ah well, this is all pretty pointless for me anyway. 
I've been a C/C++ programmer for nearly a decade now,
and I haven't missed an increment/decrement operator
one bit since trying Ruby.

I love this language ;)
