Doesn't look like installing Readonly::XS helps: 
use warnings;
use strict;
use Readonly;
use Readonly::XS;

Readonly my $DBG_INFO    => 0x0004;
Readonly my $DBG_KEYS    => 0x0008;
Readonly my $DBG_RAND    => 0x0080;

Readonly my $_debug_ops => ($DBG_RAND | $DBG_KEYS | $DBG_INFO);
printf ("%04x\n", $_debug_ops);
printf ("%04x\n", $DBG_RAND | $DBG_KEYS | $DBG_INFO);

__END__
$ perl -wl 640089.pl
Argument "=28" isn't numeric in printf at 640089.pl line 12.
