Has anyone here used Io?

I recently installed the Io programming language and find it quite intriguing. It is almost like playing with Lego, the way you construct your objects and stuff.

Definitely this language should be checked out if you are interested in neat programming languages.

Hey guys, check this out:
Io> plus := method(a, b, a + b)
Io> plus(1, 2)
==> 3
Io> getSlot("plus") message next setName("-")
Io> plus(1, 2)
==> -1
Put that in your production code LOL!
