   First of all: local procedures using local variables in an *outer*   
   stackframe are problematic. Such a language feature deserves much   
   work, in detail when you also want to allow to use local procedures as   
   callbacks (procedure pointers). I'd drop that from my language.   
      
   Otherwise John already explained how to pass a reference to outer   
   stackspace(s) to the nested procedure, as an hidden parameter. But   
   this added parameter will disallow to give away references to the   
   local subroutine, because the caller then doesn't know about that   
   parameter.
