This is absolutely true. These are the reason why D is useful to 
me.

That said, I have mixed feelings since it's also true that, 
should these features be introduced by default, they would help 
with many bugs I see that cause security issues. As much as I 
like my job I would be happier if it weren't needed.

It wouldn't fix everything since the most common issues are at a 
much higher level (such as forgetting to protect a web page with 
authentication). It would help with memory corruptions and 
possibly race conditions since it would incentivise safer use of 
multithreading.

I'd be stuck though. Please don't. I don't want to write Go :p
