 We reuse the Parfait code at compile-time, to create the data for the compiled code.
 To do this the compiler (re) defines the object memory (in parfait_adapter).

 A step back: the code (program) we compile runs at run - time.
 And so does parfait. So all we have to do is compile it with the program.
