Comment (by lftabera):
I created another method substitutying the Integer with int. Then used the
following code. To get an idea.
{{{
sage: K1=QQ['x,y']
sage: K2=PolynomialRing(QQ,'a',5)
sage: K3=PolynomialRing(QQ,'b',30)
sage: f=K1.random_element()
sage: g=K2.random_element(degree=10,terms=24)
sage: h=K3.random_element(degree=100,terms=10**5) #quite long time
sage: vf=random_vector(ZZ,2)
sage: vg=random_vector(ZZ,20)
sage: vh=random_vector(ZZ,30)
sage: %timeit f.weighted_degree(vf)
sage: %timeit f.weighted_degree_int(vf)
sage: %timeit g.weighted_degree(vg)
sage: %timeit g.weighted_degree_int(vg)
sage: %timeit h.weighted_degree(vh)
sage: %timeit h.weighted_degree(vh)
}}}
I do not have a strong opinion. Integer does not overflow, but int is
faster (but also slow) and behaves like degree method (also returns int).
