I highly doubt that any such feature is introduced to save keystrokes. If you want to save keystrokes, Ruby is probably not your language. And you also really need to invest some time in your editor/IDE. The sugar is that it removes redundancy and adds DRY: > Every piece of knowledge must have a single, unambiguous, authoritative representation within a system. Now, the value for DRY is minimal here: `referer_acceptence_header: referrer_acceptance_header` is quite easy to spot (and there too: if these are your bugs, you probably need to invest some time in your editor/IDE), but avoiding it alltogether in the language is always nice.
