Bear with my confusion about your response.  Are you saying that CPython documentation bugs cannot be submitted here, or that this does not constitute a CPython documentation bug?  I assume the latter.  But then, can you tell me where to find the correct CPython documentation after I read the following quote from PEP 277?

http://www.python.org/dev/peps/pep-0227/
    "Implementation

    XXX Jeremy, is this still the case?

    The implementation for C Python uses flat closures [1]."

In case you might care about a user confusion ...  Your reply left me puzzled that PEPs that have reached the standards track would not be considered part of the CPython documentation distribution.

Thank you,
