You know...I've played the private/public/protected game in C++
faithfully for about five years (though mostly in private <wink>), but
in retrospect, I just really can't see much point to it.  (And don't
even get me started on that bogus "friend" thing--with a friend like
that, who needs enemies? <wink>)

The only thing of all of that I can see any real point to now is
"private", which I use to mean "this stuff is Plutonium; pure toxic
nuclear waste; the most deadly substance on the planet: don't touch it
unless you're trying to save the good people of Chernyobl, at the
possible cost of your own life".

I think Python has some sort of convention or system for that, but I've
never used it.

To be honest with you, my major disinterest in Java (besides all the
hype <0.9 wink>) is driven by the fact that its libraries seem to be
replaced on a daily basis; frankly, it takes me too long to understand
any given system to invest my time in one that will be obsolete before I
even get done reading the "Learn Java Libraries in 21 Days" book that
just repeats the online documentation.

Are you sure?...  I read the other day that Microsoft bagged on their
Java product.
