I've been thinking about events for the 0.8 series of SQLObject. I'm thinking about using PyDispatcher, but there's still some open questions. Jim Fulton actually got me thinking about events a while ago, in lieu of "hooks"... PyCon 2003, I guess. He made a presentation at PyCon 2005 too, but it didn't resonate in the same way, it just seemed too low level; PyDispatcher isn't very complex, but it's a bit higher level. I think Jim was really proposing that higher level systems be built on the low-level systems, but I dunno... it's too abstract then to mean much to me.

Anyway, that's what I'm thinking about. The events, at least to start, would be at a fairly low level -- covering things like creating classes and instances, maybe creates and deletes.

One concern I have is that anything can be listening for an event, so it's hard to know what all will be effected. When that event is raised it's open season, anything could react. Especially when there's feedback from the events (which I'm planning on) I can imagine confusing ensuing. So... I dunno. Logging?
