Or, in my language, 0**n as n->0.
I don't think this issue arises here, because this discussion
is about the value of x**n for *integral* powers of n when
x is real.
Loren Meissner made a similar remark (to the effect of
"be careful about functions with two variables"); I
think the same consideration applies.
