Ok, maybe I was too specific, I wanted to ask what is the current 
support of RAII in whole std while using @nogc, not in the 
language itself.

It's all about perception, if you don't know that something 
exists or is capable of doing something then you will never 
choose it. Sure it's a benchmarking game, but game people refer 
to a lot on reddit or hn. And people still think D is slow so 
they don't even consider using it. It's really about marketing.
