"Defacto standards" are meaningless. The semantics of any procedure call are completely opaque from just looking at an API let alone a code snippet, especially the API of a dynamically typed language, and doubly-so if that language supports monkey patching.

So the original post's dismissive argument claiming one sequence of syntactic sugar and one set of procedure calls is clearer than another is just nonsense, particularly for such a trivial example.

Maybe it is. That's an empirical question that can't be answered by any arugment I've seen in this HN thread.
