I think Maciej left out an "only" in that sentence. If you say "only C", then the sentence makes sense, even when applied to modules that *can* only be written in C (for CPython). That is, not having a Python version is bad. Necessary in many cases (or not worth the cost, for external library wrappers), but wouldn't it be nicer if it wasn't necessary? > This PEP has a flavour to me of the old "100% pure Java" ideal, where > Java coders expected everything to be reimplemented in Java, avoiding > any native code.

The Pythonic ideal contains quite a bit of pragmatism, so yes, that is an exaggeration of the goals of the PEP, certainly.

That might indeed be a useful exercise, especially since other implementations (or even perhaps CPython developers) may want to contribute Python-only versions and/or tests for things that would have been affected by the PEP. I don't have time to do it right now, but if I can pry any time loose I'll have it near the top of my list. -- R.
