Okay, I'm with you. That jibes with my understanding of OOP in
a universal sense. In ActionScript, however, classes *are* properties
of the _global object, which is what prompted my question. Programmers
in general may agree to avoid global variables in principle, and what
I'm hearing is that A

What I don't understand -- and I hasten to say I have no opinion on
the matter, yet -- is why _global is so shunned. After all, _global is
exactly where AS2 classes are located. Is this a religious issue? Is it
because of how _global gets shared (or not?) among dynamically
loaded SWFs?

yeah its yuck, though i use it myself here and there for the cheap hack that
it can be. i think generally most programming languages (or the prgrammers
using those languages) look down upon global vars. i think the idea is that
it pretty much destroys encapsulation and object-oriented principles.
I suppose it's the use of variables in _global. That's what I avoid.
Else, 5 years later, when you've got extensive classes, and something
ddoesn't work, it might be because some variables overwrite one
another in _global. That'd take almost forever to debug.

In the last few days, I've seen a handful of people refer
apologetically to use of the _global object. To paraphrase: "I'm in a
situation where I have to use _global variables," or, "We all know _global
is a no-no, but I'm tempted to use it in this one weird case," etc. In
general, this
