Class Methods:

new(name, member...)

Creates the new subclass of the Struct class, which is named name and returns it. Each subclass has access methods for the structure attributes. For example:

dog = Struct.new("Dog", :name, :age)
fred = dog.new("fred", 5)
fred.age=6
printf "name:%s age:%d", fred.name, fred.age
