in reply to Re^2: Scurbbing a string

Yes. But remember that $ctl in that snippet is the equivalent of the OPs $pure, not the variable being cleaned.
Still, I guess they could legitimately contain meta chars. If the OPs $pure variable(s) are sourced from outside of his program or genuinely might contain meta characters, then a quotemeta would probably be appropriate.
Indeed, it might be good if that were mentioned in the eval tr example in perlop.

In the absence of evidence, opinion is indistinguishable from prejudice.
