When trying to fix the compile error I have with the None type keywords I had

closer look at tables and the generation/translation process. I can fix my
issues by changing remove_named_arguments.py to always include all default
arguments not just up to the last keyword argument. The nice thing is that
this
means defaults in python and C++ don't necessarily have to match this way.
I don't think that's the way to go. Considering arguments with default None
value, you should provide an overload for those. for instance in
empty_likes.hpp:
template <class E, class dtype>
auto empty_like(E const &expr, dtype d = dtype())
-> decltype(empty(sutils::getshape(expr), d));
template <class E>
auto empty_like(E const &expr, types::none_type d = builtins::None)
-> decltype(empty(sutils::getshape(expr),
types::dtype_t<typename E::dtype>()));
Hope it helps?
