how to override the new/initialize method for a struct?

[jtprince]

How do I make a custom initializer for a struct object? This is how I would expect it to be accomplished (but this does not work):

Dog = Struct.newbark, :bite) do
def initialize(*args)
super(*args)
bark = "really loud" unless bark
end
end

dd = Dog.new
p dd.bark # => should be "really loud" but is nil

So, structs have no initialize method... I tried some other approaches but no luck yet. Can anyone figure out how to do this?

I think your problem is just on one line. Make this change:

self.bark =3D "really loud" unless bark

Without that change you are assigning to a local variable and not to the =
'bark' attribute/instance variable.
