You're isolated the problem fairly well: how to implement

I don't know how to implement it due to potential interactions with
`local-expand'. More accurately, I don't know how to specify a
`begin/letrec-syntaxes+values' and `local-expand' that play well

I think the way to attack this problem is to try to get rid of
`local-expand', eventually.
