Comparison to Python | Cobra - just blogged for completeness, as the language has some interesting ideas. Specifically, I would like the contracts as explicit syntax, Python only allows similar things in a roundabout way. However, the language is otherwise just one of the many niche languages. And honestly, Python is more than just the indentation - what about the very sophisticated metaprotocol of Python in the various niche languages? PyPy in combination with Rpython and the new ctypes for pypy is much more interesting.
