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?
