NAME

Perl::Review::Policy::Variables::ProhibitPackageVars

DESCRIPTION

Package variables are globally visible, thus exposing your implementation to prying eyes. 'Tis better to use accessor methods or static subs to change the state of things in your package.

This policy assumes that you're using strict vars so that variables declarations are not package variables by default. Thus, it complains you declare a variable with our or use vars, or if you make reference to variable with a fully-qualified package name.

  $Some::Package::foo = 1;    #not ok
  our $foo            = 1;    #not ok
  use vars '$foo';            #not ok
  $foo = 1;                   #not allowed by 'strict'
  my $foo = 1;                #ok
