Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write "q{}" instead of "''".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Don't use quotes for an empty string or any string that is pure whitespace. Instead, use "q{}" to improve legibility. Better still,
created named values like this. Use the "x" operator to repeat characters.
$message = ''; #not ok
$message = ""; #not ok
$message = " "; #not ok
$message = q{}; #better
$message = q{ } #better
$EMPTY = q{};
$message = $EMPTY; #best
$SPACE = q{ };
$message = $SPACE x 5; #best
CONFIGURATION
This Policy is not configurable except for the standard options.

Perl::Critic::Policy::ValuesAndExpressions::RequireUpperCaseHeredocTerminator - Write " <<'THE_END'; " instead of " <<'theEnd'; ".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
For legibility, HEREDOC terminators should be all UPPER CASE letters (and numbers), without any whitespace. Conway also recommends using a
standard prefix like "END_" but this policy doesn't enforce that.
print <<'the End'; #not ok
Hello World
the End
print <<'THE_END'; #ok
Hello World
THE_END
CONFIGURATION
This Policy is not configurable except for the standard options.
