Subject: A code snippet: Controlled retry

I sometimes find myself retrying operations when in a networked
situation (e.g., maybe server isn't up, just try again).

I just wrote this little bit of code.

Tell me what you think... I'm sure it can be improved.

Cheers,
Hal


   def try(quiet=true,times=5,secs=1,&block)
     count = 0
     catch :finished do
       begin
         block.call
       rescue => err
         puts "Error was: #{err}" if not quiet
         count += 1
         throw :finished if count > times
         sleep secs
         retry
       end
     end
   end
