There was an article in Dr. Dobbs' about 10 years ago, where perl was
referred to as the Swiss Army chainsaw. <g>

*snarl*
There is *no* excuse for lots of globals. Pass your stuff. The most
complicated programs I've ever written in perl (I guess that was the
billing system for a very small telecom, 600-700 lines or more) had less
than 10 globals, and maybe less than five (it's been 6 years since I was
there, so I don't remember). Using globals is *lousy*, *lazy* programming,
and I wouldn't trust folks that write anything more than a 20 or 30 line
script to program *anything* until they'd gone back and internalized
modular coding. And then I'd review their code for the next six months....
