There must be a better way to do this.

One issue with this is that it can't extend to == and !=. I wonder whether that invalidates the idea...

True. This is a problem for eg: SymPy where == and != are structural equivalence and Eq gives an expression. Numpy however is consistent and implements == and != and returns a numpy array of bools.
