Lambda the Ultimate

I'm feeling lonely around here.

A few more posts are floating around, so follow the links from these two blog posts.

In gbeta, object metamorphosis coexists with strict, static type-checking: It is possible to take an existing object and modify its structure until it is an instance of a given class, which is possibly only known or even constructed at run-time. Still, the static analysis ensures that message-not-understood errors can never occur at run-time.

It is possible to define relations between classes, e.g., to specify that the class MyPoint must be a subclass of YourPoint (without committing to exactly what classes they are). This makes it possible to define a kind of constraint graph of classes.

I can see the big red XML box on the top left, but I don't see an RSS feed for the forum or recent posts. Does such a thing exist?

Mark Pilgrim has written an excellent book on Python.
It is available on line and is in the book shops.

The section on introspection is likely to be of interest
to us.
