NAME

Perl::Review::Policy::Variables::ProhibitPunctuationVars

DESCRIPTION

Perl's vocabulary of punctuation variables such as $!, $., and $^ are perhaps the leading cause of its repuation as inscrutable line noise. The simple alternative is to use the English module to give them clear names.

  $| = undef;                      #not ok

  use English qw(-no_match_vars);
  local $OUTPUT_AUTOFLUSH = undef;        #ok

NOTES

The scratch variables $_ and @_ are very common and have no equivalent name in English, so they are exempt from this policy.
