"Mixing initialized and uninitialized data bloats the executable size"? I was reading the source for this pacman game written in Zig and Sokol, and there's a comment on line 401: "keep the big undefined data out of the state struct, mixing initialized and uninitialized data bloats the executable size". From what I gather, this has to do how static memory is stored in the binary, which is a little beyond me but makes sense. But what should I do about it? The repo has it segregated into its own top-level struct, but why can't it be a sub-struct like the other things in State? It doesn't seem very ergonomic to have a second state struct of members whose only unifying feature is that they're "too big".
