Comment (by vittucek):
I am in the middle of bugfixing right now.
sage: R.<q> = ZZ[]
sage: A2 = WeylCharacterRing(['A',2], base_ring = R, style="coroots")
sage: [A2(x) for x in [-1]]
[-1*A2(0,0)]
This is because the type of the coefficient -1 is
sage.rings.polynomial.polynomial_integer_dense_flint.Polynomial_integer_dense_flint
and the test c < 0 evaluates to False
Is this a bug or intended behaviour?
