Re: [Visualpython-users] Let's hash out the documentation for restrictive imports

This proposal assumed that the "libvisual" file was in the visual
folder, in which case I thought that relative imports were now
favored, for various reasons. As I understand it, the main issue is
that there could be a module named "foo" at a higher level in the
search path, in which case "import foo" might not pick up our foo, but
someone else's foo. Have I misunderstood something?
