On: Rust's Ugly Syntax

[sivizius]

For the record:

    let squares: Vec<_> = numbers.iter().filter(x => x >= 0).map(x => x * x).collect();

is not valid Rust, but this is:

    let squares: Vec<_> = numbers.iter().filter(|&&x| x >= 0).map(|x| x * x).collect();

[satvikpendem → sivizius]

The above seems more like valid TypeScript instead.
