Sachin, I responded to your question in the PR. I think I'll go with Gilbert's approach. As far as the second part was, we will take the first approach - the reason is that we have three different classes that handle vectors - and we need to be able to apply those operation on each class.
Also, there's another problem. Right now, we can do Vector.coord_sys and get the CoordSys object. But now, we can't do this because the CoordSys object hasn't been constructed at the time of initializing the vectors. -- You received this message because you are subscribed to the Google Groups "sympy" group.
