;;;; One directory, two names — where one of the two is a package's.
;;;;
;;;; pkg-two-aliases.flan has both import forms in the entry file, where the
;;;; clash is written down in one place and easy to see. This is the case that
;;;; only exists once a package may import a package: area/ imports shape as
;;;; [shape], this file imports the same directory as [sh], and the two names
;;;; are pages apart. The rule is the same one — a directory reached twice
;;;; arrives under one set of names, or every declaration in it exists twice —
;;;; and it has to hold through a chain, because that is where nobody can see
;;;; both halves at once.
