It seems to me like you should just be using D, not "Better C-style D"? All those features are not in BetterC because they need a garbage collector, but they are of course in D proper. For smaller projects, I'd recommend just ignoring the GC until you run into actual issues with it, then optimizing for the specific issues.

That's easy to say, but as long as C++ and other languages can do those things without a garbage collector, D seems somewhat less attractive. (I'm not the OP but I've had a similar experience with D.)

  You can do all of them without a garbage collector - you just have explicitly manage the memory yourself.

As I understand it, garbage collection is kind of a non-starter for games programming because it leads to unpredictable pauses in what should be a low-latency, interactive application.

  It is optional however and you can use custom allocators to get around it.

  Infognition has found that if you keep the D GC heap under 100k the max pauses will be about 1 ms. The means to reduce GC usage have only grown more diverse in recent years: - std.experimental.allocator - @nogc to ensure, well, no GC usage - various things built on placement new (`emplace`) - GC profiling with -profile=gc, will display number of allocations and size None of this existed when people were already making high-performance systems with D...

  You can have low pause, fully concurrent GC even in Java. A GC can utilize read barriers and overall eliminate stop-the-world pauses. --- A popular example is minecraft that uses mainstream G1 GC.
