+=head1 NAME
+
+Perl::Critic::Policy::BuiltinFunctions::ProhibitVoidGrep - Don't use C<grep> in void contexts.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+C<map> and C<grep> are intended to be pure functions, not mutators.
+If you want to iterate with side-effects, then you should use a proper
+C<for> or C<foreach> loop.
+
+  grep{ print frobulate($_) } @list;           #not ok
+  print map{ frobulate($_) } @list;            #ok
+
+  grep{ $_ = lc $_ } @list;                    #not ok
+  for( @list ){ $_ = lc $_  };                 #ok
+
+  map{ push @frobbed, frobulate($_) } @list;   #not ok
+  @frobbed = map { frobulate($_) } @list;      #ok
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
