Hi, is it possible (or planned) to add operators to a ctypdef struct?
Using the WrappingCPlusPlus example I would like to be able to do: cdef c_Rectangle a = c_Rectangle(1,2,3,4) a=a+a but adding c_Rectangle __add__ "operator+"(c_Rectangle right) to c_Rectange does not work. I don't want to use the Python wrapper class because I don't want the operator to produce a PyNumber_Add call. Will it be in the long run possible to wrap a C++ linear algebra template library like Eigen (1) or NT2 (2)? This would be very nice because one could very easy speed up numpy code. E.g. in numpy a,b,c,d=[N.random.random(100000) for i in range(4)] #just creating sample data a*b*c*d #element wise multiplication is pretty slow because the multiplications are done after each other and thus cache is used poorly. By doing the same expression with either template library, the expression templates make it just one for-loop and even SIMD it.
