NAME

Perl::Critic::Policy::Variables::ProhibitLocalVars

DESCRIPTION

Since Perl 5, there are very few reasons to declare local variables. The only reasonable 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
