Python equivalent of 3v4l
Probably a crazy idea that PHP developpers won't care much about but I'd love to be able to run and compare snippets of Python on all the versions/with various interpreters so a 3v4l equivalent for Python would be awesome!
Among the main implementations : CPython, PyPy, IronPython, Jython.
As a side-note, if you find this using google, tox is useful to run code on various versions of Python but you obviously need to have them installed.

I would also love to see this for Python and Node.
I'd also love to see something similar for shell scripting. I'm willing to do work to help. For instance, I was hoping that you used something like Docker containers in the back end. Then if you had different versions of bash available you could have a container filled with alternate bash versions and run the script over and over in the container, capturing output.
