I'm really glad we're starting to see compile-to-Python languages crop up. Don't get me wrong, Python is a great language, and the community around it is fantastic, but it's missing key functional/concurrency features that would make certain problems much less tedious to solve. For instance, I love the built-in use of persistent data structures in Mochi--that's something that's sorely missing from the Python standard library.
