Well, the disadvantage of such "involuntary" initialization is fact that in some cases, compiler is not able to optimize out the zero assignment, thus resulting in negligibly lower performance. IMO, same reasoning is true for local variables...

And then, estetically, I really dislike the anomaly that

int x;

and

int x = int();

are different things...
