Sounds good to me, Joe.

I've also been thinking similar thoughts for some time. I regularly
see people going to extreme lengths to protect themselves from
themselves. It often fails because it adds unnecessary bulk and
complexity in exchange for the false sense of security that following
a method brings with it.
Take "information hiding" as one small example. In theory it's
reasonable that _some_ data should be encapsulated and accessed only
through strictly defined interfaces. In practice, though, it's often a
case of interring trivial functionality deep inside a perilously
constructed wall of cruft.
I've seen lots of C++ and Java programs that really should have been
very simple and clean. They end up being complicated because the
majority of the program consists of small pieces of simple
functionality trying desperately to contact each other through nearly
impenetrable walls of "protection". When you're not in the mood to
laugh at it, it's a truly pitiful spectacle.
And there's a dreadful law here -- it was made
by mistake, but there it is -- that if anyone asks
for machinery they have to have it
and keep on using it.
