Ok, I just realized that "delegate" can also be pointer to a non-static 
nested function...  Duh.  So my question should have been -- why doesn't 
this work?

int delegate(int delegate(inout ElemT))
reversed(AggregateT,ElemT)(AggregateT array)
{
     int _innerFunc(int delegate(inout ElemT) loopBody)
     {
         int done = 0;
         for (int i = array.length-1; i >=0; i--)
         {
             done = loopBody(array[i]);
             if (done)
                 break;
         }
         return done;
     }
     return &_innerFunc;
}
   ...
foreach(real r; reversed!(real[],real)(areal))
{...}

Compiles but gives:
"Error: Access Violation"

I'm not totally clear on how pointers/objects are handled in D.  It 
looks the call to reversed() is maybe creating a copy of the data?  If I 
put in printfs the pointer value is different from that of the original 
int[].
