#6468: [with patch; needs work] FiniteField_prime_modn.__call__ should raise an
error, rather than return an error
------------------------------+---------------------------------------------
Reporter: SimonKing | Owner: SimonKing
Type: defect | Status: assigned
Priority: major | Milestone: sage-4.1.1
Component: basic arithmetic | Keywords: Finite field, call

Comment(by SimonKing):
Gotcha!
The following nasty example triggers the error:
{{{
sage: class foo_parent(Parent):
....: pass
....:
sage: class foo(RingElement):
....: def lift(self):
....: raise PariError
....:
sage: P = foo_parent()
sage: F = foo(P)
sage: GF(2)(F)
(<type 'exceptions.TypeError'>, 'error coercing to finite field')
}}}
I will produce a patch, adding doc tests to the call method (it is
currently lacking any doc tests!), and also adding the nasty example with
reference to this ticket.
