Perl::Critic::Policy::UsereContributed:PerlcDocumentales::ProhibitLocalVars(3)

NAME
       Perl::Critic::Policy::Variables::ProhibitLocalVars - Use	"my" instead
       of "local", except when you have	to.

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

DESCRIPTION
       Since Perl 5, there are very few	reasons	to declare "local" variables.
       The most	common exceptions are Perl's magical global variables.	If you
       do need to modify one of	those global variables,	you should localize it
       first.  You should also use the English module to give those variables
       more meaningful names.

	   local $foo;	 #not ok
	   my $foo;	 #ok

	   use English qw(-no_match_vars);
	   local $INPUT_RECORD_SEPARATOR    #ok
	   local $RS			    #ok
	   local $/;			    #not ok

CONFIGURATION
       This Policy is not configurable except for the standard options.

NOTES
       If an external module uses package variables as its interface, then
       using "local" is	actually a pretty sensible thing to do.	 So
       Perl::Critic will not complain if you "local"-ize variables with	a
       fully qualified name such as $Some::Package::foo.  However, if you're
       in a position to	dictate	the module's interface,	I strongly suggest
       using accessor methods instead.
