I meant that if we really had an (accurate) error msg
saying that the plist wasn't proper then in order to
test that for each `plist-put' or whatever we'd have
to traverse every plist argument, to see if it really
is proper.
To test that `(a b c)' isn't a proper plist we'd need
to check that the number of elements is even.
We could of course have a `plistp' predicate without
using it to test during `plist-put' etc.
