If you know only expression X will raise the exception you can use  
the modifier form

some_code
some_exception_raising_call rescue nil # This is evil
continue_blissfully_unaware_of_whether_an_exception_was_raised

Also retry does not return to the statement that raised the  
exception, it jumps to the begin

begin
   # retry will put you here
   some_code
   some_more_code
   raise_an_exception
   even_more_code
rescue
   retry
end
