       Perl::Critic::Policy::CodeLayout::ProhibitQuotedWordLists - Write "qw(foo bar baz)"
       instead of "('foo', 'bar', 'baz')".


       This Policy is part of the core Perl::Critic distribution.


       Conway doesn't mention this, but I think "qw()" is an underused feature of Perl.  Whenever
       you need to declare a list of one-word literals, the "qw()" operator is wonderfully
       concise, and makes it easy to add to the list in the future.

           @list = ('foo', 'bar', 'baz');  #not ok
           @list = qw(foo bar baz);        #ok

           use Foo ('foo', 'bar', 'baz');  #not ok
           use Foo qw(foo bar baz);        #ok


       This policy can be configured to only pay attention to word lists with at least a
       particular number of elements.  By default, this value is 2, which means that lists
       containing zero or one elements are ignored.  The minimum list size to be looked at can be
       specified by giving a value for "min_elements" in .perlcriticrc like this:

           min_elements = 4

       This would cause this policy to only complain about lists containing four or more words.

       By default, this policy won't complain if any of the values in the list contain non-word
       characters.  If you want it to, set the "strict" option to a true value.

           strict = 1


       In the PPI parlance, a "list" is almost anything with parentheses.  I've tried to make
       this Policy smart by targeting only "lists" that could be sensibly expressed with "qw()".
       However, there may be some edge cases that I haven't covered.  If you find one, send me a


       This policy was formerly called "RequireQuotedWords" which seemed a little counter-
       intuitive.  If you get lots of "Cannot load policy module" errors, then you probably need
       to change "RequireQuotedWords" to "ProhibitQuotedWordLists" in your .perlcriticrc file.
