Thank you, o Monks, for that illuminating discussion of Taint.

Based on what I have read so far, I definitely need to start using taint for some of my work.

I'm a bit confused how to set this up though. I can get taint with

perl -T
[download]

from the dos prompt. But I like to control things at the script level. When I "use Taint" in my code, the program dies because there's no taint package installed.

There is a taint package on CPAN. But when I try

ppm
install Taint
[download]

no repository is found with this package/directive.

Can taint mode only be turned on from the shell with -T? Or does Taint not play nicely with ActiveState and Windows?
