Symmetric Function coercion issue #9755
Description
The following was reported to me by Nicolas Thiéry and Lenny Tevlin.
R.<q,t> = ZZ[]
R = FractionField(R)
P = MacdonaldPolynomialsP(R,q,t)
Q = HallLittlewoodQ(R,t) # or Q or P (Qp = H)
Ph=HallLittlewoodP(R,t)
SF = SymmetricFunctions(R)
SF.inject_shorthands()
Q(s.one())
Traceback (click to the left of this block for traceback)
...
AttributeError: 'int' object has no attribute 'subs'
The same error occurs with Ph(s.one()), although P(s.one()) works.
