The basic problem is that kwds is a regular, unordered dict:
def f(**kwds):
print(type(kwds))
>>> f()
<class 'dict'>
----> Hi Eryk,
Yes, I realized this later that evening (probably thanks to can of cold beer :-)). But there is hope: https://www.python.org/dev/peps/pep-0468/ . Do you know if there is/will be a "from __future__" to backport that behavior? We're using Python 3.5 now.
Thank you!
Albert-Jan
