Results in an error on e79d7e0:

test.zig:5:22: error: expected type '*const [0:0]u8', found '*const [2:0]u8'
            0 => "up"[0 ..],
                     ^
test.zig:5:22: note: pointer type child '[2:0]u8' cannot cast into pointer type child '[0:0]u8'
            0 => "up"[0 ..],
                     ^

Still gives an assertion failure if you fix the type error:

pub fn main() void {
    var data: u8 = 0;
    const x = .{
        @as([]const u8, if (data != 0) "" else switch (@truncate(u1, data)) {
            0 => "up",
            1 => "down",
        }),
    };
}
