Strange. It works for both myself and Ben.
> I'm a little worried that if the changes required replacing the inner
product in weyl_dimension method there could also be failures in
weyl_characters.py too which also depend on the same inner product.
The only problem with it was that it only worked for the ambient space and
we want it for all weight lattices. If that is not an issue for
weyl_character, then it hopefully does not change anything there!
