Hark. This Py_XDECREF shouldn't be there, I don't know how it got there. The
whole point of 'release', with conventional semantics, is to /not/ decrement the
reference count.
p_ = 0;
return result;
}
};
Sorry for posting unfinished code,

PS: "pyni" was a good name. But in use! When I thought about adding the "s" as
disambiguation I thought the pure shock value of that was funny in a way, but
now it doesn't seem funny. Is "pytes" (Python Extension Support) a good name?
