User.rb

# So we have something like this :

class User
  class << self
    def find_by_sql(sql)
      rows = @@connector.execute(sql)
      # => [[1, 'Marc']]

      rows.map do |row|
        attributes = match_columns_to_values(row)
        # match_columns_to_values returns a Hash if I recall
        new attributes
      end # => <#Enumerable:[[1, 'Marc']]:map>
    end
  end
end

class TestClass
  class << self
    def	test_method
      self.class # => Class
      [[1,'Marc']].map do
	self.class # => Class
	new({}) # => #<User:0x007fc413906b20>
	new({ id: 1,name: 'Marc' }) # => ArgumentError : wrong number of arguments ( 1 of 0 )
      end 
    end
  end
end
