Is doco wrong on ifEnum.isEmpty() ?
I am confused about isEmpty() on enumerables. RTFM implies isEmpty() is the opposite of isNext():
But the two do not stay in sync:
Seems that (and i am hoping that) the actual meaning is: isEmpty() returns whether the object has no elements (regardless of where next pointer currently is).
Is this correct? I am asking for realz, got a list - want to check if it is empty and o.isEmpty() sounds as a better/properer way than checking o.count() = 0.

IsNext() as Boolean
Returns true if there is a next element
IsEmpty() as Boolean
Returns true if there is not a next element
But the two do not stay in sync:

false true

1

false false
