| Yes, that's what I said. In the current scope, unset arranges for the

| previous scope.
Were I you, I would simply change the "in a previous scope" behaviour to
match the "in the current scope" behaviour. That makes it consistent,
and rational.
I cannot believe that there is anything anywhere which depends upon the
current weirdness.
I'd also forget "remove" as anything that unset is supposed to achieve,
and I would change "appear" to "be" in the description of the current scope
behaviour.
