I'm just curious on why this feature has been held for so long since it's been flagged for inclusion back in the 0.49 release (and now 0.52), it's the addition of "$0" for messages, seems like there's something still "wrong" with it? => https://github.com/pure-data/pure-data/pull/347 I ask because I've been improving the documentation of handling "$0" in Pd, and it'd be much easier with it. 

I also got a couple of new PRs that promote quick/minor changes to code that I consider 'bug fixes' from a documentation point of view: 1) Get rid of useless [bang~] inlet (https://github.com/pure-data/pure-data/pull/1471) cause I don't think it makes sense to document that it has no functionality (and this won't break any patches); 2) add bang method to [atan2] (https://github.com/pure-data/pure-data/pull/1465), because all other similar math/binary operators do this and it's just harder and more confusing to document a special inconsistent case. This is specially needed now that I'm adding references subpatches with info on i/olets and methods.

cheers
