------
-
-The `half_open_range_patterns` feature allows RangeTo patterns
-(`..10`) to be used in appropriate pattern matching contexts.
-This requires also enabling the `exclusive_range_pattern` feature.
-
-It also enabled RangeFrom patterns but that has since been
-stabilized.
-
-```rust
-#![feature(half_open_range_patterns)]
-#![feature(exclusive_range_pattern)]
-    let x = 5;
-    match x {
-        ..0 => println!("negative!"), // "RangeTo" pattern. Unstable.
-        0 => println!("zero!"),
-        1.. => println!("positive!"), // "RangeFrom" pattern. Stable.
-    }
