BURIEDP contentslist
BURIED? contentslist
outputs TRUE if the first procedure, variable, or property list named
in the contents list is buried, FALSE if not. Only the first thing in
the list is tested; the most common use will be with a word as input,
naming a procedure, but a contents list is allowed so that you can
BURIEDP [[] [VARIABLE]] or BURIEDP [[] [] [PROPLIST]].
