-A tuple type defines various named *fields* and an *order* of the fields.
-The constructor ``()`` can be used to construct tuples. The order of the
-fields in the constructor must match the order in the tuple's definition.
-Different tuple-types are *equivalent* if they specify fields of

+The default type to pack different values together in a single
+structure with a name is the object type. An object is a value type,
+which means that when an object is assigned to a new variable all its
+components are copied as well.
 
-The assignment operator for tuples copies each component. The notation
-``t.field`` is used to access a tuple's field. Another notation is
-``t[i]`` to access the ``i``'th field. Here ``i`` must be a constant

+where all of its fields can be initialized. Unspecified fields will
+get their default value.

+Tuples
+------
+
+Tuples are very much like what you have seen so far from objects. They
+are value types where the assignment operator copies each component.
+Unlike object types though, tuple types are structurally typed,
+meaning different tuple-types are *equivalent* if they specify fields of
+the same type and of the same name in the same order.
+
+The constructor ``()`` can be used to construct tuples. The order of the
+fields in the constructor must match the order in the tuple's
+definition. But unlike objects, a name for the tuple type may not be
+used here.

+Like the object type the notation ``t.field`` is used to access a
+tuple's field. Another notation that is not available for objects is

+Inheritance
+-----------
 
-Like tuples, objects are a means to pack different values together in a
-structured way. However, objects provide many features that tuples do not:
-They provide inheritance and information hiding. Because objects encapsulate
-data, the ``T()`` object constructor should only be used internally and the
-programmer should provide a proc to initialize the object (this is called
-a *constructor*).
-
-Objects have access to their type at runtime. There is an
-``of`` operator that can be used to check the object's type:
+Inheritance in Nim is entirely optional. To enable inheritance with
+runtime type information the object needs to inherit from
+``RootObj``.  This can be done directly, or indirectly by
+inheriting from an object that inherits from ``RootObj``.  Usually
+types with inheritance are also marked as ``ref`` types even though
+this isn't strictly enforced. To check at runtime if an object is of a certain
+type, the ``of`` operator can be used.

 Inheritance is done with the ``object of`` syntax. Multiple inheritance is
