You are correct. I meant to remove the $stdout wording before
posting :-(

I actually use $stdout.puts to override the trash for debugging
code wrapped by trash. I would normally write code witout the
$stdout in  which case trash works fine (on Windows and UNIX
at least). The output would (should) be trashed with the following
code.

def trash

   begin
      defout = $defout
      $defout = File.open('/dev/null', 'w+')
      yield
   ensure
      $defout.reopen(defout)
   end

end

trash do
   puts "hello !" # Remove $stdout. from Guy's code.
end
