Io programming language 2013.12.04
An Open Source, dynamic and small prototype-based programming language for Linux
Io is a pure object language inspired by Smalltalk, NewtonScript, Act1, LISP, Lua and Self programming languages. It has a small memory footprint and it’s reasonably fast, when compared to Python, Perl or Ruby.
Among its features, we can mention an incremental garbage collector (weak links supported), a differential prototype-based object model, exceptions, dynamic typing, ANSI C implementation, multi-state, actor-based concurrency, and 64-bit clean.
