Why the fast_* slots?

[Mildred Ki'Lya]

Hi,

I think that generally the fast_ slots make comparisons using the =
(identity) operator while the non fast slots use the == (equality)
operator. That's the same difference between == and .equals(other) in
Java. I saw this in DICTIONARY and SET

Now, because CHARACTER is Expanded, the = and == operators have the same
results, as a consequence the slots are the same.

Now, I don't know why these slots are present, I suppose these slots may
overwrite slots in generic parent prototypes.
