I love stuff like this… but then again, I have a thing for obscure and unusual languages. Some ultra-quick impressions:

• So far, it looks minimalistic and flexible.
• Borrows more than a little bit from Io. (Not that that is a bad thing…)
• Not sure I like the “licks”, but I will withhold my judgement until I know the language better. You’d think that in a language as dynamic as this, special syntax would not be necessary… but as the article points out, there may be problems with that.
• Apparently “monkey patching” is allowed, much like Ruby and Io. Dangerous…
• Interestingly, variable names can contain arbitrary UTF-8 characters. I can think of a few problems with this. On the other hand, it seems refreshing to be able to break out of the tired (letters, digits, underscore) set of choices.

I tried to build and install Potion before on OS X, but ran into some issues… will need to try again sometime.
