       Perl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching - Always use the
       "/m" modifier with regular expressions.


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


       Folks coming from a "sed" or "awk" background tend to assume that '$' and '^' match the
       beginning and end of the line, rather than then beginning and end of the string.  Adding
       the '/m' flag to your regex makes it behave as most people expect it should.

           my $match = m{ ^ $pattern $ }x;  #not ok
           my $match = m{ ^ $pattern $ }xm; #ok


       This Policy is not configurable except for the standard options.


       For common regular expressions like e-mail addresses, phone numbers, dates, etc., have a
       look at the Regexp::Common module.  Also, be cautions about slapping modifier flags onto
       existing regular expressions, as they can drastically alter their meaning.  See
       <> for an interesting discussion on the effects of
       blindly modifying regular expression flags.
