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.
