If you don't have state of the art GC, it's a burden to have in your language since it'll cripple performance, GC pausing threads, collection becoming slower as your heap grows and memory fragmentation for example D doesn't have state of the art GC, it perhaps should focus on its strengths, being a better C/C++ and embrace the concept of allocators https://dlang.org/phobos/std_experimental_allocator.html https://dlang.org/phobos/std_experimental_allocator.html To me D shine with its -betterC mode, it completely strip the runtime, giving you a great low level language to work with, a great better C/C++, I would have quit D a long time ago if it didn't have this compiler flag
