Still an insane data structure, and I'm still learning Zig, so I can't promise this is precisely equivalent to the C, I got as close as I could and am unwilling to try and compile, let alone build, such a type.
No one would actually do this unless they needed `extern` compatibility. Ignoring the fact (pointed out in the Fine Article) that no one would use anything vaguely like this, a more Zig native version might be
const foo: [_][8]**fn() [][]const u8
seq[array[8, ptr ptr proc(): ptr seq[ptr char]]]]
I believe dcl mimics the cdecl program.
char*[]*function()[8][] foo;
