* WIP: Unique https://github.com/D-Programming-Language/phobos/pull/3225 and RefCounted (can't seem to find the PR - where is it?)
already got pulled https://github.com/D-Programming-Language/phobos/pull/3171
Worth adding:AFAIK unique(?) and refcounted are completely usable in @nogc, and most of the unit tests likely can be marked @nogc for them to help prevent breakage.
