This is why I wanted to ask the group before making the pull request. As for Rafael's question -- it is no different from writing the methods out, but either is delegate. I just found that many times where I would have used delegate I ended up writing out the individual methods only to add || = "". So, I thought others might use it as well.
As for Matt's questions: (1) It's not clear (to me) how this should interact with passing multiple attributes to `delegate`: The way I wrote it all of the delegated methods passed would get the default values so: delegate :foo, :bar, :to => :person, :default_value => "" delegate :baz, :to => :person foo => "" bar => "" baz => nil (2) Also, should the default value be returned if :allow_nil is set and the delegated-to object isn't present?
