Rails article helper - "a" or "an"

There is now a gem for this: indefinite_article.

None that I know of but it seems simple enough to write a helper for this right? Off the top of my head

def indefinite_articlerize(params_word)
    %w(a e i o u).include?(params_word[0].downcase) ? "an #{params_word}" : "a #{params_word}"
end

hope that helps
