example on member coercions

[hjblok]

The note on member coercions includes the following example using a subclass of an Array:

class Book
  include Virtus

  attribute :title, String
end

class BookCollection < Array
  def <<(book)
   if book.kind_of?(Hash)
    super(Book.new(book))
   else
     super
   end
  end
end

class Library
  include Virtus

  attribute :books, BookCollection[Book]
end

library = Library.new
library.books << { :title => 'Another Introduction to Virtus' }

When I run this example library.books.class is an Array and not a BookCollection. So I added a default value to the attribute :books:

attribute :books, BookCollection[Book], default: BookCollection.new

Should this be added to the docs?

Not really, it's been fixed in master.
