MacOS 13 support with Zig · contributing

Got some time to look at Roc again and saw the warning about no MacOS 13 support, but tried running the rocLoves* examples anyway and the Zig one fails. I'd like to help fix this. @Anton I see you added the warning to the Markdown files - do you have any extra context on the issue with Zig 0.9.1 on MacOS 13? More info about the error below.

I'm running MacOS 13 on Apple silicon with Zig 0.9.1 installed with asdf. This is the error I see, but I'm not sure what the "Darwin is handled separately..." part means:

🔨 Rebuilding platform...
An internal compiler expectation was broken.
This is definitely a compiler bug.

Hi @doubledup, here is our old conversation when the error first showed up. This is the relevant zig issue.

It looks like zig 0.10.1 solves this issue, but introduces compiler errors. Is there any reason to not upgrade to zig 0.10.1? I'd be willing to put in the work to fix the compiler errors and testing it out. Wanted to see if there was a reason not to update zig.
