   No special measures are required.   
   You look `fun up in the current search order, and say "isn't unique"   
   You look `fun up in the all wordlists, and say "isn't globally unique".   
      
   In ciforth you have an iterator for namespace (VOCABULARY's) e.g.   
   \ Print all namespace (voc) names in existence.   
   : .VOCS 'ID. FOR-VOCS ;   
      
   Now replace the execution token ID. by a word using SEARCH-WORDLIST .   
      
   You ask for something simple.   
   That is neither here nor there.   
   Use a simple Forth, then it is easy.   
   If you use a difficult Forth, all tasks are difficult.
