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

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
.
