The official rule was that import* at other than module scope has undefined
behavior.  Still is.  The complication comes from spelling out the accidents
of the 2.1 implementation that intersect with the accidents of the 2.0
implementation, for the benefit of whatever users may have been violating the
rules without realizing it.

Would you prefer that we let you dope that out for yourself?  I'd be
delighted to stick to the official rule, not catering at *all* to code that
ignored the Ref Man.  Then we could replace the entire explanation with a
one-line quote from the manual:  "you cheated; you got caught; tough luck".
