   I don't know that it ever really improved performance, but it still is   
   useful.  I use the switch() form for backing out of situations having   
   complicated setup where processing isn't possible unless all the setup   
   steps succeed.   
      
   I keep track of how many setup steps successfully complete, and then,   
   whatever the exit situation, I jump into a Duff switch that tears it   
   all down in reverse order of the setup.
