What is the technical definition right now?  And which part is 
implemented and which parts are future changes?

As far as I understood it, lambda's introduced a complete new scope so 
you could shadow variables above, whereas procs produced a more loose 
scope.  But perhaps I misunderstood.  Anyone have a good definition/example?
