And, in some ways, PyPy. I still think it is the sanest way to implement Python. It makes me sad that I have to write C to make any meaningful changes to Python. Same goes for ruby. Rubinius was such a nice project. Hacking on schemes and lisps made me realize how much more fun it is when the language is implemented in the language itself. It also makes sure you have the right abstractions for solving a bunch of real problems.

    PyPy is python implemented in python. It is fast.

      PyPy is python implemented in RPython, which is technically a python subset. It's so restricted it might as well be a different language though.
      - bjoli 6mo ago
        It is restricted in a way that you would restrict yourself to write high speed software in most languages, and I found it is not that restrictive compared to C that you would have to use if you were to write a fast Python library.

        oh for sure, but I still feel like telling people pypy is written in python is misleading. it's written in something significantly like python, but it's not python.

        > technically a python subset So it can just run under CPython? If so, then that isn't too misleading.
        bjoli 6mo ago
        Yes. It can run under Cpython (2.7).

        PyRPy is just less catchy sounding

      https://pypy.org/ https://pypy.org/ It lags behind CPython in features and currently only supports Python versions up to 3.11.

      The fact that it's written in python is often brought up in order to explain its name. But really, it's much less interesting than the fact that it has a tracing JIT. If it were called PyJIT I'd bet it would be clearer and more obvious that it's fast. And people would prob get less hung up on the distinction between python/rpython.

  Well, one could rewrite Python (perhaps piece by piece?) in Shedskin. Shedskin is very nearly Python compatible, one could say it is an implementation of Python.
