Isn't this what gives us the "<!-- Variable XXXX is undefined -->"  
type output in the templates? That's much more helpful - and  
sometimes a quick fix for null checking in a hacked together  
prototype - than it spewing a property exception and failing to build  
the page...

...or am I missing something?
