R.multiset

matchAll [1, 2] as R.multiset integer with
| $n :: $ns -> (n, ns)
---> [(1, [2]), (2, [1])] or [(2, [1]), (1, [2])]

matchAll [1, 2] as R.multiset integer with
| #1 :: $ns -> ns
---> [[2]]

R.set

matchAll [1, 2] as R.set integer with
| $n :: $ns -> (n, ns)
---> [(1, [1, 2]), (2, [1, 2])] or [(2, [1, 2]), (1, [1, 2])]

matchAll [1, 2] as R.set integer with
| #1 :: $ns -> ns
---> [[1, 2]]

pureRand

pureRand 1 6
---> returns a random integer uniformly distributed over the closed interval [1, 6]

rands

take 10 (rands 1 6)

---> [3, 3, 6, 3, 3, 4, 5, 5, 1, 4] for example

randomize

randomize [1, 2, 3]
---> [1, 2, 3], [1, 3, 2], [2, 1, 3], [2, 3, 1], [3, 1, 2] or [3, 2, 1]
