   Interesting enough - considering this "dual xt" idea, 4tH has *ALWAYS*   
   been "dual xt". All compilation behavior is in the compiler and all   
   execution behavior is in the interpreter. Note 4tH *only* contains   
   primitives. The Forth layer is what you build with these primitives,   
   since both the compilation behavior and execution behavior is coded in C.
