NAME
       Perl::Critic::Policy::RegularExpressions::RequireDotMatchAnything - Always use the "/s" modifier with
       regular expressions.


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


DESCRIPTION
       When asked what "." in a regular expression means, most people will say that it matches any character,
       which isn't true.  It's actually shorthand for "[^\n]".  Using the "s" modifier makes "." act like people
       expect it to.

           my $match = m< foo.bar >xm;  # not ok
           my $match = m< foo.bar >xms; # ok


CONFIGURATION
       This Policy is not configurable except for the standard options.


NOTES
       Be cautious about slapping modifier flags onto existing regular expressions, as they can drastically
       alter their meaning.  See <http://www.perlmonks.org/?node_id=484238> for an interesting discussion on the
       effects of blindly modifying regular expression flags.
