The longobject2.diff patch probably doesn't apply cleanly any more.
Anyone interested in updating it?
I think this patch looks like a promising beginning, but there's still
quite a lot of work to do. The main concerns at the moment are:
(1) the huge numbers of Py_DECREFs and Py_XDECREFs. Some refactoring
might help here ("goto" isn't all bad: it's fairly common to use lots of
"goto error" statements in Python's source code).
(2) I suspect that many of the operations could be turned into in-place
operations on digit vectors, thus saving lots of object allocations and
deallocations. This should also help out with (1).
I'm not yet 100% sold on getting subquadratic division into Python---it
remains to be seen how much complexity it adds. If it makes it easy to
implement subquadratic integer <-> string conversions that would be a big
plus.
