This file demonstrates the high degree of flexibility that Superx++ has

with entity access.

The _object() syntax allows you to place any expression within the parentheses

as the object being accessed.

The _member() syntax allows you to place any expression within the parentheses

as the member being accessed.

The _method() syntax allows you to place any expression within the parentheses

as the method being accessed.

The _attribute() syntax allows you to place any expression within the parentheses

as the attribute being accessed.
