Goals seems very similar and from a cursory reading: - automem is much further along on many points such as: attribute forwarding, @nogc, @safe, DIP1000, allocator support, ranges, support for GC roots, and exists since 6 years. - numem is designed to allow C++ programmers to feel at ease, with a bit less runtime use maybe. Containers own their elements, like C++ containers (not sure how it is in automem). We plan a std::map-like.

I don't think there are that many of them. The non GC dynamic array would be a good fit here.

Nice, thanks for sharing, it'll be very useful for the C++ developers who want to give D a try

Indeed with numem you can have a relatively "C++11" experience with scoped ownership, which we intend to make use of because without GC it's easy to be plagued by leaks in user code.
NuMem - safe(r) nogc memory managment
NuMem 0.5.4 has been released, numem is a new library I am developing with contributions from Auburn Sounds/p0nce. It's meant to provide safer ways of writing nogc code, which is sometimes neccesary when the D garbage collector would be an unoptimal choice. NuMem currently features: * C++ style smart pointers (unique_ptr, shared_ptr, weak_ptr) * C++ style vector type (with support for moving unique_ptr's in!) * Alternative for new and destroy; `nogc_new` and `nogc_delete`. * A string alternative built on the vector implementation * Automatic null-pointer handling, for easy passing of strings to C. * A `minimal_rt` mode meant for environments where only a tiny subset of the D runtime is present, with custom handling of class destruction that doesn't use TypeInfo. * Eg. the port of D I'm making for the SEGA Dreamcast. We plan to add more memory management utilities, thereby making writing completely GC-less D code a lot more user-friendly. You can find the package here https://code.dlang.org/packages/numem Additionally, the `yxml` package uses numem's smart pointers and strings. https://code.dlang.org/packages/yxml
