Io - Small, prototype-based programming language

Io is a small prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects) and Act1, Self, and NewtonScript (actors and futures, differential protos, inheritance by delegation).
 Features:
 -  small (~12K lines)
 -  pure object language
 -  reasonably fast (comparable to Python, Perl, Ruby)
 -  differential prototype-based object model
 -  untyped
 -  incremental garbage collection
 -  exceptions
 -  ANSI C implementation (except for inline directive)
 -  embeddable
 -  multi-state (multiple independent VMs can run in the same application)
 -  coroutines (light wieght threads)
