   You have that backward, it must be:   
      
   { "the square is:" print dup * cr } : Square   
      
   If there is one thing to preserve in Forth that is the   
   convention that defining words can parse new names in   
   the dictionary by forward scanning, without those considered strings.   
   Here { introduces a denotation, without being a PREFIX (" recognizer"),   
   such as 0x in 0xDEADBEEF is. It is the same within a definition like   
   numbers and nowadays strings.   
      
   { "the square is:" print dup * cr } CONSTANT orang_utan   
   orang_utan DUP : Square  : quadrate

   I have create a language on that principle, e.g. meta   
   accepts 2 xt's a build and a run one. meta is the mother of   
   all defining words:   
   { , } { @ } meta CONSTANT   
   { CELL ALLOT } { } meta VARIABLE   
   { 2 CELLS ALLOT } { } meta 2VARIABLE   
   { } { EXECUTE } meta :   
   { } { } meta DATA     \ My favorite.   
      
   CREATE DOES> is the right idea, an object with an allocation   
   part and a behavior, but the syntax is akward beyond despair.   
      
   I have a backlog, busy with preserving projects dating from the   
   80's, so don't expect a publication soon.
