Comment (by burcin):
I don't see what the expected behavior here is. Do you want `sum()` to
return `infinity` instead of raising a `ValueError` with the message `Sum
is divergent.`?
Note that if you state that the variable is positive, the first example
also raises an error:
{{{
sage: n = var('n')
sage: assume(n>0)
sage: sum(n, n, 0, infinity)
...
ValueError: Sum is divergent.
}}}
