Supposition: taint is associated with the variable, not the value. Assigning to the variable doesn't clear the taint flag. Creating a new variable does. That's why my example worked.

Solution #1 is to fix Perl, if that's the proper remedy. Solution #2 is not to reuse $file to hold the contents of $1.
