/**
* Includes the prototype object of another object in the prototype
* chain of objects created with the calling Function object.
* <p>
* Used with constructors to establish multi-level prototype-based
* inheritance (much like class-based inheritance in Java). To that end,
* this method adds a <code>_super</code> property to the function to refer
* to <var>Constructor</var>, the constructor of the parent prototype.
* Likewise, instances constructed with the resulting function have a
* <code>_super</code> property to refer to their constructor.
* </p><p>
* NOTE: Because of this, you need to use the constructor's
* <code>_super</code> property if you want to refer to the parent's
* constructor in the instance's constructor; using the instance's
* <code>_super</code> property would result in infinite recursion,
* and ultimately a stack overflow. You may call the parent's
* constructor explicitly within the constructor of the child, using
* the (equivalent of the) <code>arguments.callee._super.call()</code>
* method (or calling it explicitly as a method of the inheriting
* prototype); in prototype methods, use
* <code><var>Constructor</var>._super.prototype.method.call()</code>
* or refer to the parent constructor directly.
* </p>
* <p><em>Not to be confused with {@link jsx.object#extend}.</em></p>
