NAME

       Perl::Critic::Policy::RegularExpressions::ProhibitSingleCharAlternation - Use "[abc]"
       instead of "a|b|c".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Character classes (like "[abc]") are significantly faster than single character
       alternations (like "(?:a|b|c)").  This policy complains if you have more than one instance
       of a single character in an alternation.  So "(?:a|the)" is allowed, but "(?:a|e|i|o|u)"
       is not.

CONFIGURATION

       This Policy is not configurable except for the standard options.

CREDITS

       Initial development of this policy was supported by a grant from the Perl Foundation.
