Well since "naturally" is an aesthetic judgement, it is hard to provide a precise definition. Rather you can provide contrasting examples and get a sense of someone else's tastes.
But the reason for my comment is that Perl has enough ways to distribute actions over lists in a concise manner (map, foreach, etc, etc) that introducing a very specialized one doesn't meet the utility threshold to be worthwhile.
But if you disagree, try to produce an example where such a method would make sense, and I'll produce an example that doesn't use the method, and we can compare. If it really is natural for your problem domain, then it shouldn't be hard to come up with a good example...
