No, because the arguments have already been transformed into a
sensible (for C) representation, so the need for manual extraction
doesn't arise. There are situations where I want to do this, but
there are very few of those, and then I can still do the callback.
You normally don't cons that much in wrapped code: C doesn't know
about Scheme data. It cares about C data.
