I was under the impression that coding-style questions are allowed here, even if they deal with a language-specific feature; but other users assert this is not the case, and that these questions should be closed. I couldn't find any explicit policy regarding this, so I'm turning to meta.
My opinion is that these sort of questions are not coding problems (which belong on SO) but squarely rest in the coding-style field, which seems to be allowed here. Not to mention that with the variety between different programming languages, every coding style question could be said to be specific to a certain (and possibly small) group of languages.
So, are coding style questions in general on-topic, and does the size of the group of programming languages they refer to matter?
