Perl::Critic::Policy::InputOutput::RequireCheckedClose
The perl builtin I/O function close returns a false value on failure. That value should be checked to ensure that the close was successful.
close
my $error = close $filehanle; # ok close $filehanle or die "unable to close: $!"; # ok close $filehanle; # not ok
