To me, return would imply that the returned value should be passed back
by the original require call, like so:

$ cat a.rb
return 42

$ cat b.rb
p require("a")

$ ruby -I. b.rb
42


That could be *really* handy, although it's not compatible with my
previous suggestion (currently languishing here:
http://redmine.ruby-lang.org/issues/4523 - any comments?). An
already-loaded file can still be signaled by a nil return value, and a
file could pretend to be already loaded (if that's at all useful) by
choosing nil as its return value...

Food for thought :-)
