The last value that was generated outside of a test clause is the result of the verb. But it's not being displayed in the verb -- it's being generated as a result. The display happens later. In other words: shuffle=: 3 :'cube [] move"0 ] 3|?~y' The [] pair will delay resolution of the value of cube until after the results from executing move have been completed.
