       Perl::Critic::Policy::Variables::ProhibitUnusedVariables - Don't ask for storage you don't


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


       Unused variables clutter code and require the reader to do mental bookkeeping to figure
       out if the variable is actually used or not.

       At present, this Policy is very limited in order to ensure that there aren't any false
       positives.  Hopefully, this will become more sophisticated soon.

       Right now, this only looks for simply declared, uninitialized lexical variables.

           my $x;          # not ok, assuming no other appearances.
           my @y = ();     # ok, not handled yet.
           our $z;         # ok, global.
           local $w;       # ok, global.

       This module is very dumb: it does no scoping detection, i.e. if the same variable name is
       used in two different locations, even if they aren't the same variable, this Policy won't

       Have to start somewhere.


       This Policy is not configurable except for the standard options.
