I really expected this to be a bug.  Because I would expect this to fail:

struct S
{
   int opApply(int delegate(ref size_t idx, ref int val) dg)
   {
     return 0;
   }
}

void main()
{
   S s;
   foreach(uint idx, int val; s) {}
}

i.e. you cannot possibly duplicate this 'feature' for a custom structure.  But
then of course, you cannot duplicate the 'no ref' aspect of the index either.
