Today's dynamic language systems have grown to include features that resemble features of operating systems. It may be possible to improve on both by unifying a language system with an operating system. Complete unification does not appear possible in the near-term, so an intermediate system is described. This intermediate system uses a common call graph to allow components in arbitrary languages to interact as easily as components in the same language. Potential benefits of such a system include significant improvements in interoperability, improved reusability and backward compatibility, simplification of debugging and some administrative tasks, and distribution over a cluster without any changes to application code.
