Perl::Critic::Policy::Community::BarewordFilehandles3pm

Overview

Bareword filehandles are allowed in open() as a legacy feature, but will use a global package variable. Instead, use a lexical variable with "my" so that the filehandle is scoped to the current block, and will be automatically closed when it goes out of scope. Built-in bareword filehandles like "STDOUT" and "DATA" are ok.

  open FH, '<', $filename;     # not ok
  open my $fh, '<', $filename; # ok

This policy is similar to the core policy Perl::Critic::Policy::InputOutput::ProhibitBarewordFileHandles, but allows more combinations of built-in bareword handles and filehandle-opening functions such as "pipe" and "socketpair".
