Comment (by tscrim):
So do you think we should raise an error message when we have incompatible
arguments, which would be a coroot with a weight/root, and coerce
otherwise? Or should we use the a^v^ = 2 a / (a, a) identification to do
the pairing? Also you'd be okay with the first would coerce move
`alpha[1]` into the weight lattice?
