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.
