You know you drive all of us OO guys crazy with comments like "just use
a global variable"?

There is a big difference between a global variable and a singleton.
You're only thinking of the access point, not the rest of the pattern.
I'd be VERY surprised if it's possible to implement a true singleton
pattern in IDL. I'd love to be proved wrong, but I don't think it's
possible with IDL's so-called "objects."
