    You'll note I said I was playing with RPython, not PyPy. In my case, I was playing with writing a small interpreter, and comparing the RPython toolchain with the Truffle/Graal framework.

    Writing RPython code, even if one is not developing or contributing to PyPy, means writing within a subset of python 2.

    > RPython ("Restricted Python") is a subset of Python 2

    https://www.pypy.org/posts/2022/04/how-is-pypy-tested.html

    And RPython's translator specifically uses pypy, and uses python 2 syntax:

    https://github.com/pypy/pypy/blob/main/rpython/bin/rpython#L...

    ... so getting the RPython toolchain (even if one is intending to improve the PyPy 3+ interpreters) requires setting up a pypy 2 interpreter. Hence the question in my post.
