But anyway, after fixing the obvious Phobos offenders, another huge step would be to get TempAlloc into druntime and used wherever possible in Phobos.How does that work? One pattern I've used a lot is, since we have a regular 60hz timeslice and fairly a regular pattern from frame to frame, we use a temp heap which pushes allocations on the end like a stack, then wipe it clean at the state of the next frame. Great for any small allocations that last no longer than a single frame. It's fast (collection is instant), and it also combats memory fragmentation, which is also critically important when working on memory limited systems with no virtual memory/page file.
Yes, that is basically it. https://github.com/dsimcha/TempAlloc/blob/master/std/allocators/region.d
