Steps to Reproduce and Observed Behavior

compile the following snippet

pub fn main() !void {
    var value: ??u8 = null;

    value = 1;
    std.debug.print("{}\n", .{value == 1});
}

const std = @import("std");

and the compiler fails with

error: failed to select cmp_eq ??u8 |(none)| dx |(none)| si
pub fn main() !void {
~~~~^~~~~~~~~~~~~~~

It doesn't fail with

pub fn main() !void {
    const value: ??u8 = 1;

    std.debug.print("{}\n", .{value == 1});
}

const std = @import("std");

Expected Behavior

The snippet should be compiled fine and prints out true
