If you're interested, there was a huge thread about this in February, starting about here:
http://lists.puredata.info/pipermail/pd-list/2009-02/067889.html
It continues, too -- it will look like the thread "dies out," but if you look later in that month there will be many more posts with the same subject.

yep, sure, it works, but, anyway, I just think it would be easier for some operations if we could use "$0" in messages, that's all...
Thanks
