           Summary: The compiler performs insufficient analysis to check
                    if a structure is actually nested

A structure should be considered nested and non-POD only if it actually needs a
context pointer. Currently this not the case:

import std.traits : isNested;

void main()
{
   struct S1
   {
      int x;
   }

   struct S2
   {
      int x;      
      void methodThatDoesntRequireContextPointer() { }
   }

   static assert (!isNested!S1);
   static assert (__traits(isPOD, S1));

   static assert (isNested!S2);
   static assert (!__traits(isPOD, S2));
}
