sorry, I changed the code accidentalness in one of my patches to make
it work... I undid the changes.
After pulling again, you should get the problem I had:
sage: ct = Cartan

Hi,
I encountered a problem with roots and coroots for the root lattice:
if I take the coroot_space of a root lattice (i.e., the root space
over ZZ), I get the coroot space over QQ. Therefore,
to_coroot_lattice_morphism and associated_coroot do not work. On the
other hand, when I fix this problem
