No, it won't work. It'll say "actual" is undeclared. https://github.com/ziglang/zig/issues/4437 https://github.com/ziglang/zig/issues/4437 is tracking the issue. I think std.testing is going to see some major changes, so it's possible this gets fixed. But going from the responses in that issue, I think that fix might be more of a side effect, since there doesn't seem to be too much sympathy for the issue as-is.
