Matchers

R.multiset: (match-all {1 2} (R.multiset integer) [<cons $n $ns> [n ns]]) ;=>{[1 {2}] [2 {1}]} or {[2 {1}] [1 {2}]} (match-all {1 2} (R.multiset integer) [<cons ,1 $ns> ns]) ;=>{{2}}
R.set: (match-all {1 2} (R.set integer) [<cons $n $ns> [n ns]]) ;=>{[1 {1 2}] [2 {1 2}]} or {[2 {1 2}] [1 {1 2}]} (match-all {1 2} (R.set integer) [<cons ,1 $ns> ns]) ;=>{{1 2}}

pure-rand: (pure-rand 1 6);=>1, 2, 3, 4, 5 or 6
randomize: (randomize {1 2 3});=>{1 2 3}, {1 3 2}, {2 1 3}, {2 3 1}, {3 1 2} or {3 2 1}
R.between: (R.between 1 3);=>{1 2 3}, {1 3 2}, {2 1 3}, {2 3 1}, {3 1 2} or {3 2 1}
R.uncons: (R.uncons {1 2});=>[1 {2}] or [2 {1}]
R.car: (R.car {1 2});=>1 or 2
R.cdr: (R.cdr {1 2});=>{2} or {1}
