Hello list.

Attached file (also available at https://gist.github.com/1652684),
implements org-babel evaluation functions for Io language
(http://iolanguage.org). It's not yet fully functional (no value
results, and session support) as I'm still learning org-mode from
developer perspective, but if you're interested, I'd be happy to
contribute it.

Best regards,
Andrzej
