Actually... that cleans it up enough and makes it nice and readable.
    def initialize(raw_field)
      if a
        a_action
      else
        b_action
      end
    rescue
      b_action
    end


Why aren't the begin and end blocks needed?  Is it because it is already
encapsulated within a method any way and if it hits rescue, the rescue block
is terminated by the method end in any case?

What I am trying to ask is "where did you learn when the begin and end are
needed and when not?" :)
