I didn't say the context was void -- 

 "Hm, Tim doesn't like grep... Maybe  just if used in void 
  context..." 

I was suggesting though that this might explain the perceived bias 
that was ascribed to Tim. 

Near violence can erupt in some quarters if map or grep or 
backticked commands are used in void context.

Quick, Tim, straighten this mess out :)
