Don't get me wrong, I love lisp, but it gives you the power to essentially create your own domain-specific language. A power that comes with both positive and negative side effects depending on the situation.
Edit: Heh, just realized there is another article on the front page arguing this.
Not that you couldn't call it a "transpiler" and consider it a new dialect of Python... Hey, the Javascript community gets away with it, why not Python?
Also, while I can't think of a normal use case, it is possible that someone intended to use (a, b, c) > (x, y, z) as a tuple comparison. ">>" or something might be safer.
I think that it could get to a state where if the debugging was figured out, and the abstractions/usability became nicer that it could be have some serious use though. Mostly the intention with this was to get something working, that can be iterated on if it makes sense.
