I don't understand what you're saying here (it's late...): the problem
is that 'import foo.bar' and 'import bar' both bring in the same
module in some situations, and they don't compare as equal. The
problem isn't with foo.bar and baz.bar both being imported as bar and
comparing as equal---or am I missing something (again)?

you mean we should always have to say "import foo.bar.baz", even when
I'm in 'foo.bar'?

if it is the above what you mean by 'the whole notion of "searching a
path"', I guess I can live with that. But if you mean we should drop
sys.path altogether--- ?
