I have a feeling this may be a lot more difficult in C++ because of 
ADL--there are simply a lot more functions to be evaluated when building 
expression trees.  Also, the standard doesn't seem to consider things 
from a compiler writer's perspective, which this three-value code 
optimization requires.
