Yes, I tried that at first, but soon after noticed that `matches` is an output
parameter, so we would have to fix up the caller to stop making assumptions
that the `--` is tacked onto the beginning. Certainly doable, but it has
potential for growing into a large CL depending on how far down the rabbit hole
we'd have to go to fix everything.
