symbolic sums with known parameters should simplify()
A minimal case:
sage: (k,n) = var('k,n')
sage: sum(abs(k*k+n),k,1,n)
sum(abs(k^2 + n), k, 1, n)
sage: _(n=8)
sum(abs(k^2 + 8), k, 1, 8)
sage: _.simplify()
sum(abs(k^2  8), k, 1, 8)
I would expect _.simplify()
or .expand()
to give me the result 162
but this does not work.
