   On modern desktop CPUs, I would probably spend the effort on   
   optimising locals more. However, the ability to provide the address   
   of a local is essential in our world. I have not inspected our code   
   base to see how many uses of a local declaration of a buffer   
   : bah   {: ... | FOO[ cell ] ... -- :}   
   there are compared to the use of the ADDR (address) operator   
   applied to a normally defined local   
   : bah   {: ... |   FOO ... -- :}   
   ...   
     addr FOO   
      
   Local buffers are remarkably useful.
