Finds the value of the next iteration(s) of an Iterator object
and increments the Iterator to the next value(s). yield_more() repeats
yield_next() a specified number of times.
Refer to the number of the current iteration in yield_more() with .iter.
yield_next(iter) yield_more(iter, more = 1L)
| iter | An Iterator object |
|---|---|
| more | How many values to yield |
An object of whatever type result evaluates to from the Iterator, or
a vector of that type in the case of yield_more(iter, more > 1L).
