That is a projected, community-localized, requirement that ignores historic evolution of the practice. It is very interesting that machines can now be more flexible and understanding about nomenclature subtleties like this than some human engineers. Since we are adding layer after layer of pedantry -- rather than 'requirement' -- 'ethic' or 'practice' would be a more effective, practical and inclusive word choice here. The subtext of this thread, that Clojure somehow isn't a "functional enough" language to be labelled a "functional" language is narrow community prejudice.
