This RFC does not even display properly. lol

This RFC does not even display properly. lol

That is addressed in the "unresolved questions". Creating a custom Rust font and/or forking Servo or Firefox to build our own Rust browser with full Emoji support would trivially resolve that problem. 🍻

It seems great for others also,not just for errors

Why stop with error handling? Changing keywords would be even more interesting. With just a few ones exchanged, e g:

pub = 🍺 (well, you can do other things at the pub too)
fn = 😄 (fun!)
struct = 🏢 (a building!)
trait = (clearly a traitor!)
mut = 🔇 (muted!)
derive = 🚗 (sitting in the front seat)

Example code:

#[ 🚗 ( De 🐛 )]
🍺 🏢 April1st {
fooled: bool
}

impl 💧 for April1st {
😄 💧 (& 🔇 self) {
println!("{:?}", self);
}
}

Quick someone, please create rfc to use unicode character for lifetime!

fn foo(a: &str¹) -> &str¹

If possible, consider compatibility with PEP 3117 for maximum synergy :)

We really need this for Redox, it makes everything much better.

I'm glad the Rust team is trying to get ahead of the curve with error messages. After Microsoft replaced their old blue screen with the super useful ASCII sad face I finally realized that the computer's emotions tell me more than an error code ever could.

As with other newly proposed features, we propose adding a feature gate for emojified error handling:

#[feature(emojification)]

Besides from a missing !, I believe this should read #![feature(🌅)] which signifies the bright new future of post-Emoji Rust.

😱⚠️ These should be

enum 🙏<T, E> {
    🍻(T),
    💩(E), 
}

😱!()

Can we close this as postponed? MIR is clearly blocking.

[burdges]

We should ask this ISO Trump++ guy to weigh in here. Is he on github?

[nikomatsakis]

After deep and thorough consideration, the @rust-lang/lang team has decided to close this RFC. It just doesn't quite fit into our priorities at this time. Maybe later!
