I find I often use delegate and many nil guards in my facades. Adding a
default_value option to delegate would simplify this, but I am interested
how others feel about it.
Implementation would look something like:
class PersonFacade
delegate :name, :to => :person, :default_value => ""
def initialize(person)
@person = person
end
end
p = Person.find
p.name => nil
f = PersonFacade.new(p)
f.name => ""
