I read this once. I read it twice. I drank some whiskey. I read it
thrice. It still doesn't make any sense. Give perl too much to do?
Filtering text and working on it is exactly what perl was designed to
do - passing something through grep and then to perl makes the baby
Jeebus weep buckets.
And as for the analogy - it dies roaring because there's nothing grep
can do that perl can't.
