rhiannon morris 3fb8580f85 re-add tightening and use it when messing with scopes
e.g. "coe [_ ⇒ A] @p @q s" should immediately reduce to "s",
but if the "_ ⇒ A" happened to use an SY it didn't.

this will still happen if a wrong SY sneaks in but the alternative is
re-traversing the term over and over every time whnf runs
