rust just got 4x more productive [shill thread]

Rust designers developed an idiom for concisely propagating errors outwards with a macro called try!:
let file = try!(File::open("file.txt"));
More recently, Rust shipped an even more concise notation for error propagation, the postfix ? operator:
let file = File::open("file.txt")?;

Just searched for ``rust error propagation'' and came across this article:

I didn't even read it but you can be sure it's hipster shit when they have a FUCKING ``IT''-LIGATURE IN THE TITLE!
