Wondering about this blog post from 2002, in which the author claims to have
rewritten the Mach kernel in AppleScript and even booted it:

I’ve never heard of being able to write a kernel in AppleScript, let alone
optimizing it for special instructions/registers. AppleScript is totally
abstracted from hardware, right? What the fuck?
