You're right, defaults would take care of those few places reducing the need to reference the arguments object entirely. I think there may be one or two exceptions, like when there's no default value but an explicit `undefined` is coerced to "undefined" but a lack of the argument becomes an empty string. I guessable default value of the empty string may cover this but I have a nagging feeling there's some exception in one of the builtin methods that defies all attempts that don't rely on arguments.length, but I can't figure out what that method might be.
