None of the ideas discussed here should be considered set in stone. This is only a draft to be used for discussion purposes. We expect many details to change over time, but the basic structure should be flexible enough to accommodate an efficient implementation.

Like Self, all computation-even an object's own access to its internal structureis performed by invoking methods on objects. However, like Smalltalk, Newspeak is class-based. Classes can be nested arbitrarily, as in Beta [44]. Since all names denote method invocations, all classes are virtual; in particular, superclasses are virtual, so all classes act as mixins. Unlike its predecessors, there is no static state in Newspeak, nor is there a global namespace. Modularity in Newspeak is based exclusively on class nesting. There are no separate modularity constructs such as packages. Top level classes act as module definitions, which are independent, immutable, self-contained parametric namespaces. They can be instantiated into modules which may be stateful and mutually recursive.
