sed's y command does not allow regular expressions. Take a look at "man tr" if you want to use ranges like that.

perl::critic::policy::regularexpressions::requirelineboundarymat
Perl::Critic::Policy::RegularExpressions::RequireLineBouUseryContributed PPerl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching(3)
NAME
Perl::Critic::Policy::RegularExpressions::RequireLineBoundaryMatching - Always use the "/m" modifier with regular expressions.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
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
CONFIGURATION
This Policy is not configurable except for the standard options.
NOTES
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
<http://www.perlmonks.org/?node_id=484238> for an interesting discussion on the effects of blindly modifying regular expression flags.
