bareword::filehandles - disables bareword filehandles
no bareword::filehandles;
open FH, $file # dies
open my $fh, $file; # doesn't die
print FH $string # dies
print STDERR $string # doesn't die
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".
Disables bareword filehandles for the remainder of the scope being compiled.
Enables bareword filehandles for the remainder of the scope being compiled.
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".
