Abstract

A virtual machine is extended to include native support for co-routines. In this manner, high-level programmers are afforded access to such functionality. More particularly, supplied is a mechanism inside the virtual machine to enable method/function state to be maintained and subsequently restored. Consequently, a method/function can be called multiple times and resume where it last left off. This provides direct support for tier splitting patterns, iterators and comprehensions, among other things.
