In Ruby you can also but executable code in class declarations. It's 
heavily used in Ruby on Rails' ActiveRecord implementation:

class Post
   has_many :comments
end

class Comment
   belongs_to :post
end

"belongs_to" and "has_many" are plain class methods. When this is 
possible you rarely need user defined attributes/annotations and similar 
features.
