I generally love the current import system for "just working" regardless
of platform, installation details, etc., but what I would like to see is
a clear import local, (as opposed to import from wherever you can find
something to satisfy mechanism). This is the one thing that I miss from
C/C++ where #include <x> is system includes and #include "x" search
differing include paths, (if used well).
