Comment (by darij):
On line 775, when you say {{{0 + p_{1} + \dots}}}, does p_{1} just mean
the variable X?
I'm surprised that this stuff is in a class named "CycleIndexSeries" --
I'd expect it to be defined for LazyPowerSeries in full generality? Of
course, it makes sense to also have a wrapper in CycleIndexSeries that
gives back the answer in the correct type.
