Hello, I read here (https://rpython.readthedocs.io/en/latest/rpython.html) that PyPy is runnable on top of CPython. How do I start PyPy so it runs in CPython?

python2 pypy/bin/pyinteractive.py

You can get help with

python2 pypy/bin/pyinteractive.py --help

It takes ~20 secs to startup. To drop into rpython, hit ctrl-c, to return to interpreted PyPy on top of CPython hit ctrl-d

In rpython you have access to "space".

Thank you very much for this information. It really helped me.
