I want a thing that has a fuzzy capability <X>. To make this easier to discuss and think about, here's a short name <Y> for that thing, and a longer definition <Z> that probably describes that thing. . Oh look, if I take the literal definitions of some words in <Y>, there's a thing that fits! Therefore <X> is solved!
