<h2>Description</h2>
<p>Demonstrates dynamically resolved properties. Uses a new feature of the Objective C 2.0 runtime: dynamically resolved methods.</p><p> </p><p>Possible uses of dynamic method resolution: faulting in method implementations that reside in dynamically loaded libraries; runtime environment specialization, such as choosing between different method implementations based on the capabilities of the OS or underlying processor; lastly language bridges could use dynamic method resolution to lazily bind their object wrapper methods.</p>
