Looking through cpython and trying to form a patch I found several differing interpretations of truncate: Lib/_pyio.py def truncate(self, pos=None): Modules/_io/fileio.c PyDoc_STRVAR(truncate_doc, "truncate([size: int]) ..."); A first semi-working patch is attached. This will allow: truncate() truncate(x) truncate(size=x) and fail on: truncate(x, size=x) truncate(x, size=y) Thoughts? ps. fileio_truncate is defined as (PyCFunctionWithKeywords)fileio_truncate, METH_VARARGS \| METH_KEYWORDS but fails with "takes no keyword arguments". How do I fix this?

ps.
