About FixedIdentitySet

I just noticed this:

(FixedIdentitySet withAll: #(a b c)) = #(a a a).

I presume that does not matter...


FixedIdentitySet also make usage of identityHash
- with a basicSize power of two
- using bitAnd: rather than modulo (because of the size being power of
two, that should be equivalent)
I guess it works because used with small size only...
Beware not using scaledIdentityHash then !


Shouldn't the read-only version really use an Array, up to a given
size greater than 0 or 1 ?

Yes, I noticed that; FixedIdentitySet was the only class other than
MethodDictionary that needed to use the unscaled primIdentityHash.

I wondered what FixedIdentitySet was used for, it seems like a very odd
beast, but I didn't dig into it.
