Class Exception is the superclass of all Exceptions, so you could rescue
Exception and catch all of them (though this is often considered the worst
practice, because it can keep you from really polishing your code).

begin
  a = nil # setup an error
  a.each {|i| puts i}
rescue Exception
  puts "Error #$!"
end
