Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write "q{}" instead of "''".
This Policy is part of the core Perl::Critic distribution.
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
This Policy is not configurable except for the standard options.
