Re: what does $|++ do here?

in reply to what does $|++ do here?

Noting also the comment about it being a toggle, the ++ doesn't make sense to me either. But in that case, I would tend to wonder if the following is what is really meant:

$| = !$|;

Which is a good enough reason otherwise to support the above idea of just assigning one to it to avoid confusion.

It was said that --$| toggles $|. While $| = !$|; is clearer than --$|, noone said anything about wanting to toggle $|.
