I share the concern. It doesn't seem obvious that the derivatives of the byte code operations would produce a computationally accurate derivative of the source function. Other than that the idea is interesting, and it would be cool to see how well it works in practice. Also, the name "nabla" would suggest that the component is designed for calculating derivatives of vector functions.
