You couldn't inherit Object>>#hash, the identity hash, because it is not unique or consistent between images.
If a class overrides with its own hash, I suppose you could use it but.. the hashes are used in where: query lookups and typically don't see querying on #hash:
myCollection where: [ : each | each hash between: 123 and: 456 ]
because it does not seem very meaningful; except in a MagmaSet or MagmaDictionary perhaps?

Hello,
Looking at the MagmaCollectionIndex, I am wondering what could prevent from using a general, default MagmaCollectionIndex implemented with the method:
MaDefaultIndex>>indexHashForIndexObject: anObject ^ anObject hash
I am sure there are plenty of reason to not do so, but I am note sure about.
