Comment (by aschilling):
Also, there is a test in the new code
{{{
sage: C = crystals.Letters(['A', 3])
sage: B = crystals.infinity.Tableaux(['A',2])
sage: T = C.tensor(C, B); T
}}}
What does it mean to take tensor products of crystals of different Cartan
type? The documentation of crystals.TensorProduct explicitly says that the
Cartan type needs to be the same!
