NAME
bareword::filehandles - disables bareword filehandles
VERSION
version 0.007
SYNOPSIS
no bareword::filehandles;
open FH, $file # dies
open my $fh, $file; # doesn't die
print FH $string # dies
print STDERR $string # doesn't die
DESCRIPTION
This module lexically disables the use of bareword filehandles with
builtin functions, except for the special builtin filehandles "STDIN",
"STDOUT", "STDERR", "ARGV", "ARGVOUT" and "DATA".
METHODS
unimport
Disables bareword filehandles for the remainder of the scope being
compiled.
import
Enables bareword filehandles for the remainder of the scope being
compiled.
LIMITATIONS
Filetest operators ("-X") can not be checked on Perl versions before
5.32, because hooking the op check function for these breaks stacked
tests, e.g. "-f -w -x $file".
