Does PyPy still release 2.7 because RPython is still based on it? I was recently trying to play with RPython for the first time, and having to remember all the

  Developing / helping contribute to PyPy may mean touching 2.7 in its toolchain which is used to implement it, but no, users using it have been able to use 3.x for a very very long time now.

    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 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#L1 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.
