Hi Vincent,

I'm the author of Io and yes, I'm a Lua fan. :-) Io's orientation towards being small, embeddable and multi-state was heavily influenced by Lua. The major difference is that Io is a pure OO language.

... I wonder how it compares to lua in term of speed ...

Here's some tests from a while ago:

Looks like Lua has the speed edge, but Io is competitive. Both appear to compare pretty well to Python, Perl and Ruby.

Cheers,
Steve
