Yeah interesting, I have seen most of these projects (mentioned in the blog post) but not looked closely at Pythran. It does say it's specifically for numeric code. That is what I hinted at in the blog post around use cases for Shed Skin vs. string- and dict-oriented code. There are quite a few numeric accelerators for Python, and I even chatted with Travis Oliphant (of NumPy) about another one he was prototyping. But there are fewer for the kind of program a shell is. mypyc and shed skin are the 2 I mentioned that are most similar. We already have an approach that works, but it just needs "labor".
