What I don't quite understand is, if it is "obvious", whether there is
a Zen, people would still code it that way(unless of course they want
to hide it from others or make it difficult to understand on purpose),
there won't be any argument of "which one is the obvious way".
And if there is an argument(or disagreement), which one is the obvious
?

I think it is more like there is a preferred way, by the language
creator and those share his view.
