Yes, I also got Python vibes. That behind said, I'm digging infix less and less over time, and I'm actually starting to crave forth syntax, just got the complete lack of punctuation...
but, I actually really like what they have going here. Seems nice and minimalist, while meeting consistent and clean.
But it's interesting, since I hadn't seen that part yet, only the loop part and some of the dynamic typing.
It gave me the impression of more of a cross between Scheme and Python.
