Right. There's no question it's a theoretical win, but the question
is how much will it speed up any reasonable program. I polled a panel
of C++ luminaries, and everyone agreed that they only use empty
parameters when the function called is `inline', and if we inline then
we can certainly elide the thing, so there's not really much win.
