Indeed. As for the question in parenthesis, yes I consciously decided
to break this "ugly hack" back then, wondering how much time it would
take for people to notice it (and hoping I'd find the time/motivation
to "do it right" in the mean time).

E.g. we could allow the interactive spec to return either a list of
argument *values*, or a list of argument *expressions* (and we could
distinguish the two by having the second be a vector instead of a list,
for example).
