It's really been a mistake for the Python core team to not figure out a better way of integration with numpy. I'm pretty sure back in the 2000s the numpy team was ready to do work on this.

Syntax integration would be great. It's such a hassle to learn two syntaxes and two data/object models to work with numpy -- as inevitably your code converts from Python objects <-> numpy objects at some point (singletons!), and it makes learners' lives much more difficult than needed.
