Duff answered ron's question in “Rc — The Plan 9 Shell”.

   12. Command grouping

   A sequence of commands enclosed in {} may be used anywhere a command is
   required. For example:

      {sleep 3600;echo ’Time’’s up!’}&

   will wait an hour in the background, then print a message. Without the
   braces,

      sleep 3600;echo ’Time’’s up!’&

   would lock up the terminal for an hour, then print the message in the
   background.
