Nested relative.  After all, the universe does too...

Queries to objects (return data in format visual, wavelength 650,
visual resolution 55cm (inverse square reduction), angle 0.345x1.131,
seperated on gamma .43) or affects to objects are passed to contained
objects, and relative containment is fluid enough that an object can
effectively fail to contain another object, placing it into its
parent's coordinate field when integrity is reduced (a breaking
fishbowl places the fish and fluid in the room's coordinate field) or
removing it into a private coordinate field upon consumption (the cat
places the fish in it's stomach...)
