The @"" issue

[devins2518]

RIP @"".

A quick bandaid was to just change relevant enums to have a none tag, however, changing them to optional enums is a valid alternative. AFAIK zig does not optimize the following to the same size just yet.

const A = enum {
    a,
    b,
    none,
};
const B = ?enum {
    a,
    b,
}

This approach could make formatting a bit nicer too, instead of needing an explicit if, we could just have a default value if it's null if that's possible through std.fmt.format.
