Comment (by hthomas):
Hi Christian--
I think !QuiverMutationType(BB,1,1) shouldn't return affine A1. They are
double edges in different senses. (Affine A1 is two arrows in the quiver
convention, while I think the only reasonable interpretation of BB,1,1 is
a double edge in the Lie convention, i.e. a valued quiver with one edge
and labels (1,2). That is to say, I think BB,1,1 should return B2.)
cheers,
Hugh
