NAME
       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.
