in reply to In Defense of Perl
A big plus in favor of perl is CPAN. It's been said (reference needed) that over 90% of any project you'll ever need to build has already been written by someone else, and it's just sitting on CPAN waiting to be downloaded.
A big negative for ColdFusion is that it's a commercially owned product, marketed by Adobe - not open source, like perl. This means they can force you to upgrade to a "new & improved" version that's totally incompatible with everything you've previously developed (they probably won't, but still, it's a risk worth considering).
