That's why I quoted their claim that the "vast majority" of Python programs run unmodified. Even PyPy barely achieves that. To really get 100x performance over Python (and even supposedly beat C) with a compiler that works on most unmodified Python code would be an extraordinary achievement.

That seems misrepresenting the original points: it can run the vast majority of python programs unmodified AND in some cases outperform Python - not at the same time.
