Not a dumb question at all. And I wouldn't dignify my ideas as a "vision"
yet. If it works well, I'll retroactively dub it a vision.  ;)

Basically the only thing missing from a YAML solution or something is
the ability to do sophisticated queries without storing all the objects
in memory at once.

Given that I may have 100,000 objects or so, I don't want to store them
all in a giant array, but I *do* want to be able to find them by the
values of their accessors.

Make sense?
