One of the first things I mentioned on this NG when looking at D for the 
first time is to ask why opEquals returns 'int' instead of 'bool'. After 
being directed to a discussion about it and Walter's explanation of the 
reason I said that I hoped that he would come to his senses and realize 
it was just plain wrong. I have not changed my opinion one whit and I am 
glad that others also realize it is wrong. Hopefully Walter has realized 
it is wrong by this time too.

IMO, even if it were so, one does not twist programming design for a 
performance gain.
