It's just a name. What you do with it is up to you -- Booleanish methods
often read well with a ? at the end, though there's nothing specific
that says it has to be true or false -- could be nil or value, or
whatever else you want to do. It could invoke rm -rf /, even, though I'd
suggest ! for that!
