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;
  }
}
