...as long as you are always 100% certain that nothing in your code nor 
any third-party library you're using locks messages when you need to 
access those virtual properties.

When you have the luxury of such assurance, virtual properties are a 
wonderful code style.

But I rarely have that luxury, so I rarely use getProp/setProp.
