hello everyone,
is there any kind of smart pointers or something in D instead of GC?

It's coming!

is it coming for real, or just for the record?

Walter has been making improvements to @safe so that he can implement some form of @safe reference counting in the language. Exactly what that will look like or when it will be done is an open question (I don't even know how much Walter knows about that), but work _is_ being done specifically with language supported ref-counting in mind.

So, is it coming? Yes. Is it coming soon? Maybe. I wouldn't bet on it, but Walter could surprise us. He could have something by dconf, or enough stuff may be required to get it working or enough other important stuff may take up his time that we don't see anything until next year. I really don't know. As it is, it's already effectively been delayed by the need to improve @safe in order to make it work - though the @safe work is pretty important in its own right.

You may want to look into https://github.com/etcimon/memutils and https://github.com/caraus-ecms/tanya (source/tanya/memory/types).

Non-atomic RC wrapper type is here

http://dlang.org/phobos/std_typecons.html#.RefCounted

and instantiator for it here

http://dlang.org/phobos/std_typecons.html#.refCounted

It can be combined with containers such as the ones in

https://github.com/economicmodeling/containers

Note that these containers have their copy constructors disabled to prevent implicit (C++ style) copying.

Andrei probably knows more about _atomic_ RC.

Further, note that `RefCounted` is not yet pure, but will soon be; https://github.com/dlang/phobos/pull/4832
