About the code, the current version is

try:

I think that we should change it to
{{{
from sage.structure.coerce import py_scalar_to_element
def is_prime(n):
return py_scalar_to_element(n).is_prime()
}}}
Right, but that's not the topic of this thread. It would still give the
same result for elements of QQ.
