New description:
See [http://ask.sagemath.org/question/26374/evaluation-fail/ this
ask.sagemath question]. Apparently Ginac says zero to the zero is
undefined but most of the rest of Sage (in accordance with IEEE) says it
is one:
{{{
sage: ZZ(0)^ZZ(0)
1
}}}
but
{{{
sage: SR(0)^SR(0)
ValueError: power::eval(): pow(0,0) is undefined
}}}
