As we prepare to merge the io-c branch, the question has come up [1] about the original Python implementation. Should it just be deleted in favor C version? The wish to maintain the two implementations together has been raised on the basis that Python is easier to experiment on and read (for other vm implementors).

Probably not a surprise, but +1 from me for keeping the pure Python version around for the benefit of other VMs as well as a reference implementation. You have been practice channeling me again, haven't you? I like the idea of having two (closely matching) implementations very much.

Agreed. In particular, this helps any projects that are focused on improving the performance of pure-Python code: they can work on minimizing the delta between the Python and C versions.
