There are 12 bits are for identity hash (and 2 more?),
and since every instance has own hash value, these bits in format
field of class is not used.
I didn't understand. Why you say there are 14 free bits in the instVar 'format' of a class? I was checking the method #format: nInstVars variable: isVar words: isWords pointers: isPointers weak: isWeak
and I don't understand that.
Thanks
