chromatic is implying if not saying right out that you spell it "PERL", you're at best sloppy and at worst incapable.
Correct, and that again doesn't disagree with what I said, and I agree with chromatic
I think both he and I are distinguishing two things which you are collapsing together. Consider that what it takes to "be a good Perl programmer" (as in, understand the language from its definition) as separate from what it would mean to work for someone who demands paying attention to detail. It's about individual vs team. He and I seem to agree that spelling it PERL means you don't get to be part of our team, even though you may be a hot-shot Perl programmer.
Does that make it clearer? That's why I challenged your statement: "PERL" is a clue that you're not a team player, even though you may be a fine "Perl programmer".
