A Python Interpreter Written in Python | Hacker News

Hacker News commenters discussed a Python interpreter implemented in Python and highlighted its elegant `getattr`-based opcode dispatch.

They noted the pattern as a practical interpreter design that also works well for extensible command-dispatch systems.

The thread also debated how accurately projects like PyPy can be described as being “written in Python.”

More broadly, the discussion underscored the value of self-hosted language implementations.
