Good point. However, there are still plenty of other ways for a 
variable to lose its value when moving from one state to another. For 
example, string to number and boolean conversions affect the string's 
value.

But if myBox happens to be a string or number your test will return 
true even though it isn't a box. With ibex.log.debug("mybox: " + myBox) 
you know for sure that myBox is non-null and is a box.

We should've done this a long time ago. It was a good idea when Charlie 
first brought it up too :)
