Additionally, and also for the default operator form, it is unclear what the
result is when the operator is noncommutative. That is, whether y[n+1] is set
to x[n+1]+y[n] or y[n]+x[n+1], or if the order is somewhat random altogether
(which would make partial_sum unusable as a potential driver for the equation
y[n+1]=f(y[n])).
