Not in principle, but anyway I think the immediate request
can be satisfied in the context of #13461 (see my previous

After the patch #13461 you can do the following:
sage: A2=WeylCharacterRing("A2",style="coroots")
sage: rep = A2(1,0)
sage: a2 = WeightRing(A2)
sage: a2(rep)
a2(0,-1) + a2(-1,1) + a2(1,0)
However the inte
Hi all,
Particle physicists love coroot style (we call it 'Dynkin labels'), so the
possibility of using it for indicating representations in a
WeylCharacterRing is great!
For consistency, what about adding a style='coroots' for
weight_multiplicities() too?
It would behave as simple as:
