I thought of this, and I disagree. The very fact of assigning
to `T t` adds the reference count you need to keep `s.t` from
disintegrating. As soon as you borrow, you increment the
count.
I'm sure many inc/dec can still be removed.
Do you agree or disagree with what I said? I can't tell.
I think I understand now. Yes, they can probably be optimized,
but that's a different issue than whether you need to protect
certain RC instances from the "tyranny" of a function call. My
whole argument is that basically you don't. Only when you split
pass directly in the call itself: "fun(x,x)", does this issue
ever matter, and it's easy to deal with.
