Finding out clones and prototypes

[oscar_lopez_p]

Hi,

I'm writing a rule-based inference engine in SELF, and some
implementation issues have popped out:

Is there a fast way to get a reference to all the clones made from an
object?. Something like executing `aClass allInstances' in Smalltalk.

Also, is it possible to, given an arbitrary object, find out the
prototype it was cloned from (or if it is itself a prototype) ?.

Thanks a LOT,

Oscar
