Just so I have my mental model correct, I'm gathering that missing/`` is a symbol that the interpreter has a special rule for -- evaluating it raises an error, as opposed to objects that evaluate to themselves or variable names that evaluate to objects. Does the same sort of thing explain the behavior of `...`? When the interpreter comes across `...` in the arguments during evaluation of a call, it trips a special argument-interpolating behavior?
