The fact that
fnmain(){let x = &4i;match x {// wanted to type `e @ &1 ... &4`
e @ &1 ... 4 => println!("Got a small value: {}", e),&val => println!("Got a value: {}", val),}}
works but
fnmain(){let x = &4i;match x {// wanted to type `e @ &1 ... &4`
e @ &(1 ... 4) => println!("Got a small value: {}", e),&val => println!("Got a value: {}", val),}}
is quite surprising. Presumably the &( is expecting a tuple pattern, should consider investigating and seeing if patterns can be parenthesized in general.
