That's because outside a BEGIN there are no bindings, because the
top-level language of a module isn't Scheme: there is no concept of
bindings there.

No, it can't.  I am not using "splice" in the sense of "can be replaced
by its context" (as I showed before, expression BEGIN is not splicing in
that sense) but in the sense of not introducing a new lexical scope.
