   I did not understand at first what this code was supposed to do, in   
   particular why you would want to perform the compilation semantics of   
   S" outside a colon definition.   
      
   After some thinking I found that this code actually relies on a buggy   
   implementation of S" which does not implement the compilation   
   semantics of the standard S" in this usage.  It's better to write code   
   that does not rely on such bugs:   
      
   : ,"  ['] s" execute  dup c,  here  over allot  swap cmove ;   
      
   ," Hello world"   
      
   or just   
      
   : ,"  '"' parse  dup c,  here  over allot  swap cmove ;   
      
   ," Hello world"   
      
   As for the argument that this is supposed to be a problem of correct   
   implementations of S": Yes, one can write code that relies on a bug,   
   for every bug.  That does not justify the bug.
