    Shouldn't the sequence presentation type allow zero-length sequences
    as well?  The doc says its for one or more objects, which is
    inconsistent with general common lisp parlance.

If there's a default available, how would you distinguish between the
user hitting Return to get the default from hitting return to type an
empty sequence?
