It's already here :


import std.stdio;

struct Test
{
    ~this() { writeln("RAII"); }
}

void main()
{
     Test t; // prints "RAII" when goes out of scope
}

He's maybe talking about reference counting because "owning" the 
resources is very faisable and simple (non gc objects are 
constructed in this() and destructed in ~this(), but the problem 
happends when you escape the owned reference as a raw pointer. At 
a time it may become dangling or even freed by another entity, 
e.g not the one which has initialized the thing.

The first reply is clearly about this (when weaselcat said "It 
becomes a bit tricky when you want class semantics with RAII"), 
because std RC is not for classes.
