Monks, I was reading How do I tell if a handle is open for writing?. Although the thread didn't go down that way, but the guy sort of indicated that select can be used on normal files. I don't think so though. For example, the following code always prints -1 - nothing writable:

use strict;
use warnings;

use IO::Select;

my $file;
open $file, ">", "somefile";
my $sel = IO::Select->new();
$sel->add($file);
my @writables= $sel->can_write();
print $#writables;

Can anyone demo the opposite?
