Hm, some very good points. First off, thanks for pointing out the stray semi-colon -- it's an artifact from cleaning up the original HTML (there used to be an > there). Second, thanks for the clarification on get_hook, I must have simply mis-read the documentation: my bad.
I'm of two minds about including the longer form of register... on the one hand, it would be more accurate, on the other, it does seem a little more confusing. It's clear that what I've got is probably inadequate, but I will have to give some thought to how much of that behavior I want to explain. That, and how best to convey it.
As for the importance of the id function, would you care to expand? I'm certainly not an expert on inside-out objects, and I've just been using it as a bit of a mantra -- when I need the ID of an object, I do it this way -- I'd appreciate more insight into why I'm doing it. I can then distill that insight down (hopefully) into primer-appropriate materials.
I call Class::Std "deprecated" on the basis that I would discourage its use to anyone who didn't really know what they were doing. I hadn't considered that others would take "deprecated" in different contexts; I will have to think about how to rephrase that.
Thanks for the link to your presentation, I will look it over and consider it for mention.
