This view is called "clickable" because, as we'll see later, every syntactical element on it is a hyperlink, which you can use for browsing.
After <code>Clickable</code> comes the <code>Flat</code> view button. The layout of the result is similar. The flat form of a class is the reconstructed class text including not only what's declared in the class itself but also everything that it inherits from its ancestors, direct or indirect. This applies to the flat form's features, which include ancestor features, but also to contracts: the flat form's invariant includes all clauses from ancestors' invariants, and the preconditions are expanded to take <code>require else</code> and <code>ensure then</code> clauses into consideration. (The <span> [[An Eiffel Tutorial|Eiffel Tutorial]] </span> explains these notions in detail.)

* Expression creation: you can now create an object within an expression. For example, you want to create an object and pass it as an argument to a function. Whereas you had to create a local variable, create the object and pass it to the function, you now simply need to pass to the function the creation expression. Here is a small example:

This is also very useful since it can improve the power of assertions.
* Mutually recursive constraints: one can now write class A [H, G->H] or class B [H -> C, G -> ARRAY [H]]. As a result, the declaration A [D, E] is valid only if E is a descendant of D. Similarly, the declaration B [E, ARRAY [D]] is not valid, if E is a descendant of D.
