</div>probably yes.<br>
There are 12 bits are for identity hash (and 2 more?),<br>
and since every instance has own hash value, these bits in format<br>
field of class is not used.<br>
<br></blockquote><div><br>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<br>
