Yes. After writing my post I discovered that 2 stage creation will not 
work for returning result from function. So my 'PS.' in fact is not 
solution.

I needed something like above. Unfortunately your solution doesn't work 
(don't know why). I get access violation in my program when returning 
'*(new A*)'.

I managed to overcome bug in DMD with below:

void func(T)() {
	static TYPE res;
	res = new T;
         return &res;
}

although it will cause memory leaks for every type for which the 
function is instantiated. So I consider bug in DMD as quite serious...

No, it won't work in my program as I must return this pointer from function.

Thanks for your post!
