I just invented an absolutely wicked way of using alloca() in the 
parent context... unfortunately frame_size is static but with 
some work, it's still an usable method since it's mutable!

struct Wicked
{
   static int frame_size = 0;

   auto Create(void* buf=alloca(frame_size))
   {
     for(byte i=0;i<frame_size;++i)
       (cast(byte*)buf)[i]=i;

     struct Frame
     {
       size_t size;
     }

     Frame* xxx = cast(Frame*)buf;
     xxx.size=frame_size;

     return xxx;
   }

   @disable this();

   this(size_t size)
   {
     frame_size = size;
   }
}
