I think this is an excellent idea. Though the do...while(false) trick is 
a rather handy one, I've always felt that it its purpose might not be 
clear enough, especially to someone who has never encountered it before. 
However, I agree with Thomas: this is a one-line macro, and it should be 
portable between all standards compliant C++ compilers. There is simply 
no need to create a library just for this feature. Perhaps you could 
expand upon it a bit?
