Why is this supposed to be such a big deal? The second example uses the language's features to be able to use shorter code. Usually there are countless possibilities for the exact same thing in every program. Personally, I would never say those who produce code with unused possibilities do "not understand" the corresponding language features. Especially when writing example code or working with less experienced programmers, I even think that using less language features for the sake of making your algorithmic idea as obvious as possible is better practice. For exmapel, I find it far more important that one decides wisely when to use a linked list at all or, if there are multiple fuctions for removal, chooses the right one for a particular use-case. Therefore everyone has to understand whats happening.
