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")?;

syntax is important, contrary to what you have been told!

I've been saying this for a long time. Kind of stupid to consider the interface you perpetually have to interact with "unimportant".
