Eh?  But I came here for an argument!  Isn't this room 12?

A couple of other things:

If these additions to int go in, then presumably the _PyLong_AsBytes
and _PyLong_FromBytes functions should be documented and made public
(and have their leading underscores removed, too).  Those functions have
been stable for a good while, and are well-used within the Python source;
I think they're robust enough for public consumption.  There may be
some additional argument validation required;  I'll take a look at this.

In the issue tracker, Josiah Carlson asked about the possibility of
backporting to 2.7.  I can't see any problem with this, though there
would be some small extra work involved in making things work
for int as well as long.  Does anyone else see any issues with this?
