Io

Io - Small, prototype-based programming language

Io is small prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects) and Act1 (differential protos, inheritance by delegation) and its decendents such as Self, and NewtonScript.

 Features:
 -  small (~8K lines)
 -  pure object language
 -  reasonably fast (comparable to Python, Perl, Ruby)
 -  differential prototype-based object model
 -  untyped
 -  dynamically scoped
 -  mark and sweep 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)
