----------------------------+----------------------------
We have
{{{
sage: K = GF(2).algebraic_closure()
sage: a = K.an_element()
sage: hash(a)
Traceback (most recent call last):
...
TypeError: ...
}}}
and this prevent resultant computation of bivariate polynomials
{{{
sage: R.<x,y> = K[]
sage: x.resultant(y)
Traceback (most recent call last):
...
TypeError: ...
}}}
