-=head1 NAME
-
-Perl::Critic::Policy::RegularExpressions::ProhibitUnusualDelimiters - Use only C<//> or C<{}> to delimit regexps.
-
-
-=head1 AFFILIATION
-
-This Policy is part of the core L<Perl::Critic> distribution.
-
-
-=head1 DESCRIPTION
-
-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
-
-
-=head1 CONFIGURATION
-
-There is one option for this policy, C<allow_all_brackets>. If this
-is true, then, in addition to allowing C<//> and C<{}>, the other
-matched pairs of C<()>, C<[]>, and C<< <> >> are allowed.
-
-
-=head1 CREDITS
-
-Initial development of this policy was supported by a grant from the
-Perl Foundation.
