Perl::Critic::Policy::RegularExpressions::ProhibitUnusualDelimiters - Use only // or {} to delimit regexps.
//
{}
This Policy is part of the core Perl::Critic distribution.
Perl lets you delimit regular expressions with almost any character, but most choices are illegible. Compare these equivalent expressions:
s/foo/bar/; # good s{foo}{bar}; # good s#foo#bar#; # bad s;foo;bar;; # worse s|\|\||\||; # eye-gouging bad
There is one option for this policy, allow_all_brackets. If this is true, then, in addition to allowing // and {}, the other matched pairs of (), [], and <> are allowed.
allow_all_brackets
()
[]
<>
Initial development of this policy was supported by a grant from the Perl Foundation.
