I don't know. I get counter-arguments here like implementing the simplest-possible arena allocator possible (just use maximum alignment for all requests) and dealing with it is too much work. My blunt thought is like, what are we, Python programmers? Might as well use Python if so. Please use Python if these details don't matter. I'm serious. I have had many C programming colleagues who would very likely write not only more correct code but possibly even more efficient with Python since they ignore things like locality of reference while stumbling over bugs they create left and right. I don't see what there is that's so scary about some simple arena allocator here if we are C programmers concerned with things like data locality and optimal instruction selection, and this is arguably much less to think about than at least the types of interfaces that require callers to explicitly free every single individual thing that the interface can return. It offers bulk deallocation over individual deallocation of a sort that's more error-prone. A proper C programmer challenges loopy calls to malloc as I see it, especially when it appears as a hotspot in their profiler. From my standpoint, there has to be more "oomph" to a rationale for still being a C programmer in 2020, and we can't shy away from things like memory allocators anymore.
