It's not quite as bad as all that. It works reasonably well in Java and C# and 
for the most part isn't a big deal, but for D, init already solves the larger 
problem of variables with garbage values, and adding forced initializations on 
top of that definitely isn't worth it - especially when it requires flow control 
and can give false positives at times.

I don't think that there's much question that Java and C#'s solution is better 
than the lack of one in C/C++. But D already has a solution and does not Java 
and C#'s on top of it.
