Ah, I think I understand a bit better.  I think treating "void" as an
event is the error: it's a state.  OTOH, the "revert to previous
state" done at the end of `let' is indeed an event.

So one is an action and the other is a state.

I don't see "unbind" used anywhere in the description of what `let'
does, nor is it a term that I've heard used (other than by yourself) to
refer to what happens at the end of a "let".
