  Wow, nice. Now I think every IDE should come with this...

  Thought I'd take a crack at it in Zig: const foo: [_][8]**fn () [*][*:0]const u8; This is an array of result-defined size, of arrays of eight pointers to fn pointers, which returns a many-item pointer to null-terminated arrays of u8. Null terminated because we're going to assume that the C data structure is properly null-terminated... 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 Which returns a slice of slices of immutable u8s, these being fat pointers which include their length.

    Nim equivalent: seq[array[8, ptr ptr proc(): ptr seq[ptr char]]]] I love having actual words instead of random punctuation soup.

  Why do I remember The C Programming Language book by K&R explaining how to write a version of cdecl? I just checked the second edition of the book and my memory seems to be wrong.

    It's not listed as cdecl and (therefore?) not findable in the index, but in chapter 5 - Pointers and Arrays - the book presents the programs dcl and undcl that translate between C declarations and English renderings of them. I believe dcl mimics the cdecl program.

  I think brackets are needed in the sentence, otherwise it is ambiguous?
