Confusing error message in case of missing var/const keyword

[dee0xeed]

Zig Version

0.10.0-dev.3842+36f4f32fa

Steps to Reproduce

Compile this code

const std = @import("std");
const print = std.debug.print;

pub fn main() void {
    z: u32 = 999;
    print("{}\n", .{z});
}

Expected Behavior

Error about missing var or const keyword

Actual Behavior

z.zig:6:8: error: expected 'while', 'for', 'inline', 'suspend', or '{', found 'an identifier'
    z: u32 = 999;
       ^~~

Obviously, the parser treats z: as a label, so this error is quite understandable, but can be a bit confusing, especially for beginners. May be it would be better to have another syntax for labels? Something like this:

label::
label#

or even

::label
#label
$label
