I personally tend to avoid using those cryptic Perl-like two character
globals. I would write the above as:

$stdout.sync = true

Incidentally, I can't find any reference to $| in the Pickake, second
edition, so I wouldn't have even known about it if you hadn't posted
this. It doesn't seem to be listed anywhere on pages 334-337, nor in
the index.
