No; I think what you need is just a blank 'rescue', not else:

   begin
     puts "do something"
     raise ZeroDivisionError
   rescue NameError
     puts "name error  #{$!}"
   rescue
     puts "else  #{$!}"
   end

Output:

   do something
   else  ZeroDivisionError

An else clause will run if there's no exception at all.

I don't have my Ruby Way on me but if it says else I think it should
say rescue.
