I try to keep a foot in each version.  _ENV for modules, now that's
easy, same as module() use.  But the case you gave showed that general
analysis would be tricky and involves tracking scope of multiple _ENV
instances.  Can be done, not sure if I want to open that front
however.  I find the new load() an adequate replacement for most uses
of setfenv.

100% will be approached asymptotically ;)  But the phrase 'nothing
more' is crucial here.
