The search() position the pos argument of a library() call requests, either given as a number or as the name of
an existing entry (pos = "package:base"). Returns undefined when there is no such argument, its value is unknown
or ambiguous, or it names an entry that is not on the search path; callers then attach at DefaultAttachPosition
(as R does, which warns in the last case).
