I had in mind "it would be complicated and messy, and probably no
easier than just implementing all of the extra methods by hand" rather
than "it's impossible". Sorry for being unclear.

I haven't written many C extensions, either, so I may be
misremembering. Also, the biggest extension I wrote, which does
implement a file-like object, was written when Python 1.4/1.5 was
current, and (still) uses the C API from then. (BTW, that's a great
tribute to the backward-compatibility that Python provides!)

Paul.
