[alt.hypertext] whatever happened to HyperClass?

At an OOPSLA a couple of years ago, Apple Computer demoed a prototype
called "HyperClass".  HyperClass was an extension of HyperCard, in
that it replaced the "background card" concept with "card classes" and
inheritance.  That is, if you defined a "card class" to have certain
fields and buttons on it, you could then define a "card subclass"
which inherited those fields and buttons (and could have new ones
of its own defined as well).  There was even a browser for card
classes.  This was written almost entirely in HyperTalk, as I recall.

However, I never heard anything more about HyperClass since then.
Does anyone know what happened to it?  Is Apple still sitting on it,
or releasing it as a product, or as PD, or what?  Also, has anyone
else ever implemented anything comparable in HyperCard, SuperCard, or
whatever?
