I clearly read between the lines differently from Allen and Sam -- but
in my defense, their reading did not make any sense to me :-P.
If f1 and f2 are in the importing code, then there is no salient
difference among the module system proposals.
And anyway, if you want to isolate things in your own code you can
always wrap those things in modules as Allen said.
Perhaps the ambient authority issue to do with import "X"; (not import
"X" as X; or import "X": f1) is the issue after all.
