zip method
Aggregate two sources trimming by the shortest source
Implementation
Iterable<Tuple2<T, T>> zip(Iterable<T> otherIterable) {
final other = otherIterable.toList();
final minLength = min(length, other.length);
return Iterable.generate(minLength, (index) => Tuple2(_l[index], other[index])).toIList(config);
}
