OK, I see. For some reason I thought this would be done on the reader
level (maybe because of the discussion we've had about the syntax to
use for foreign identifiers in macro output (in the memoizer)).

Unfortunately, I don't have time now to think that through. I guess
it does feel a bit awkward that we remove the read syntax for empty
