The last line looks ambiguous, BTW, hadn't even noticed it before. Is that an array of int pointers or a pointer to an array (pointer)? We should make sure the way this is declared is really obvious and not unexpected to C users. > What would be the benefit of this?

The reasoning is that the C syntax is error prone and less readable than it could be, because you have to spot stars in the right places of a potentially long list of variable names to know if something is a value or a pointer. If there was only one type declaration, right after the cdef, it would be much clearer. It would just say: "this is a list of variables declared as int*", not mixing any further types into it. Also, C is only second nature to some people. A great many people actually use Cython specifically to *avoid* having to write C.
