<snip, regarding aq_chain>
So nobody (including the various Products I have installed) uses this incredibly useful attribute. I have numerous places in my source where I loop through aq_parent attributes.
A good question is whether aq_chain really should be a public interface. It was added (I think) as a debugging aid rather than necessarily to be used by application code. This is probably one for Jim to answer (I've CC'ed him on this). If Jim thinks it should be part of the public interface, then someone should add a documentation bug report on this so that Amos and Michel can see that it is included in the right places.
It'd be nice to have even a mention in the acquisition documentation. Poking around the Acquisition C source tells me that there's another attribute, aq_inner, that isn't documented either.
I think aq_inner is a public interface - this should also be a doc bug report. Before anyone asks, note that 'aq_uncle' is _not_ part of the public interface, and is only an exercise in Jim having fun :^) Brian Lloyd brian@digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
