pypy

pypy가 무엇인지에 대한 설명 중 하나.

"The PyPy interpreter is written in RPython, and is compiled into C by the RPython translator, which is written in Python and run on CPython or PyPy.

So you can use CPython to run RPython to translate PyPy to C, which you compile and gives you your initial binary version of PyPy. That's how you close the loop."
