Comment:
Why doing something that complicated for dealing with strange exponents?
Why not simply
{{{
if input is not an integer:
convert to an integer
do the exponentiation
}}}
Why are you special casing degree 0 polynomial? If I understand correctly
these examples won't behave similarly
{{{
sage: R.<x> = QQ[]
sage: ((x+1)^2)^(1/2)
-> TypeError
sage: ((R(2))^2)^(1/2)
-> 2
}}}
Which is weird.
