Hi, Some APIs, either due to age or design, deal out an Iterator and nothing else. And sometimes, all I care about (in tests, for example, or if the list is a set of aliases) is the first object.
The method IteratorUtils.first(Iterator) is a shorthand for IteratorUtils.get(Iterator, 0). I do not plan to add last(), the obvious sibling to such a method, YAGNI for now.
