+=head1 NAME
+
+Perl::Critic::Policy::ValuesAndExpressions::ProhibitEmptyQuotes - Write C<q{}> instead of C<''>.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+Don't use quotes for an empty string or any string that is pure whitespace.
+Instead, use C<q{}> to improve legibility.  Better still, created named values
+like this.  Use the C<x> operator to repeat characters.
+

+  $message = $SPACE x 5;  #best
