exclusive_range_pattern

The tracking issue for this feature is: #37854.

The exclusive_range_pattern feature allows non-inclusive range patterns (0..10) to be used in appropriate pattern matching contexts. It also can be combined with #![feature(half_open_range_patterns] to be able to use RangeTo patterns (..10).

It also enabled RangeFrom patterns but that has since been stabilized.

    let x = 5;
    match x {
        0..10 => println!("single digit"),
        10 => println!("ten isn't part of the above range"),
        _ => println!("nor is everything else.")
    }
