C-c C-c on settle inside sand-sim/sim.flan declared settle, but the running
program only ever knew it as sim/settle. The form spliced as a brand-new
unrelated name, the evaluation answered ok, and nothing changed. Sand's
simulation lives in a package, so the one thing worth tuning live was the one
thing that silently did nothing - and reported success while doing it.
Load now records what alias each package directory was imported under and what
names it owns, because a file on disk does not say what it is called from
outside; the importer chooses that. A session looks the editing file's
directory up in that table and qualifies the incoming forms through Load's own
qualify_decl, so a redefined settle lands on sim/settle and its call to
move-grain lands on sim/move-grain, by the same rule the import used. A name
the package does not own - the prelude's - is left alone.
Derived from the path rather than sent by the editor, which is where this
departs from CIDER's ns key: a Clojure namespace is declared in the file, but a
Flan alias is not written anywhere the editor can see it. One directory
imported under two aliases is refused with the reason instead of resolved to
either.
