Sounds innocent enough.

I ALMOST included a comment something like "I also use global variables".
Like a lot of things, it's not global variables but
global-variable-abuse that's the problem.

It happens when a programmer refuses to be disciplined about scoping
and/or allocation. Rather than think about where some bit of info is
needed, they throw everything into one big pot.

Yep ... changed (or stomped on) by anything in the system (or application).
