Re^3: Printing regular expression variable

[ww]

"...my own CGI untainting library which uses regular expression variables like qr/^.*$/ to validate incoming data."

Err, your example regex validates nothing; untaints nothing. If it's merely a simple example that occured to you for the purposes of your question, fine; if you believe it's doing something useful, you err.

I thought that was obvious, what would be the point of tainting the input and then just using ^.*$ on everything?
