   And, to continue with old terminology, PL/I has "downward" funargs   
   (passing a function into a procedure), but not upward (returning a   
   function from a procedure). It's the programmer's responsibility to make   
   sure the function's environment is in scope when called - just like it's   
   the programmer's responsibility to make sure a pointer's storage is   
   allocated when it's dereferenced.
