I'm still hitting this bug on dmd 2.073.0:
https://issues.dlang.org/show_bug.cgi?id=13009

I'm having trouble creating a minimal repro, but the error is:

Error: std.typecons.RefCounted!(MyPayload, cast(RefCountedAutoInitialize)1).RefCounted.refCountedPayload called with argument types () matches both:
typecons.d(5198):  std.typecons.RefCounted!(MyPayload, cast(RefCountedAutoInitialize)1).RefCounted.refCountedPayload()
and:
typecons.d(5190):  std.typecons.RefCounted!(MyPayload, cast(RefCountedAutoInitialize)1).RefCounted.refCountedPayload()


Can't the second overload just be put in an 'else' for the 'static if'?:

Managed to get a repro working.
Commenting out the alias 'X' makes the error go away.
If someone can confirm my sanity, I'll file a bug for this.

struct S {
    struct Payload {
        int[] data;
    }

    RefCounted!(Payload, RefCountedAutoInitialize.yes) payload;
    alias X = typeof(payload.data[0]);
}

int main(string[] argv) {
    return 0;
}

I think the smart ref is better: https://github.com/huntlabs/SmartRef

Pretty decent implementation.

It's a shame that things like "make_shared_from_this" aren't properly possible in D. I think it's a small price to pay for not having to deal with multiple inheritance though.

I considered writing my own ref counted pointers as well. Among those considerations were the thought that I should make it "make_shared" by default, and leave wrapping windows HANDLE's and whatnot to a separate primitive. This obviates the need for the second pointer since the ref count _is_ the payload.

Weak pointers in D would be nice too, but I assume it won't be necessary if D ends up getting built in ARC. Also, I don't have any use for them right now.

Just reopened the old bug.
Good talk guys ;)
