Question

B::Lint doesn’t like while (<>) {do stuff}, docs show nasty injection attack due to its internal use of the evil 2 argument open. Is there an easy way to make this usage safer? I have a lot of minor scripts that use this.

Answer 1

You can use ARGV::readonly. It will allow for safer usage of the diamond operator.

ARGV::readonly – make <> open files regardless of leading/trailing whitespace and/or control characters such as |, >, amd <.
