While self: Bar also works, but it is not typical and has different behavior. It is better to use self: *Bar

@unional You may be right, but that seems to disagree with this previous Ziglings issue: #89

Here's an example from the Zig docs:

    pub fn dot(self: Vec3, other: Vec3) f32 {
        return self.x * other.x + self.y * other.y + self.z * other.z;
    }

I'm pretty sure a printMe() method would be more correct without the reference since it does not modify the original value?

[unional]

I see. That sounds right. I'm still learning zig and this seems to be zig specific.

I create this PR because the comment and the code in this exercise does not match.

Maybe another way is to create one more exercise to demonstrate this, and update the comment section in this exercise to a mutable example, so that the comment and code are consistent. :)

@unional Oh, I see what you mean! You're right, the comment and code don't match here. I think I'll make a new issue to re-work the comment on this one. There may be other places where this is no longer consistent. Thanks!

[unional]

Sounds good. thx!

btw I did some streaming on going through your exercises: https://www.youtube.com/watch?v=ORR10_c7IKM&list=PLTLdF9P_MLntirxSOWhJoMAiitnCGbKzw

Just to share. Thanks for creating them. 😉

Very nice. Maybe you should add a note that you are giving a spoiler with your video. 😉

giving a spoiler with your video.

Haha, sure will do. 🌷
