O que costuma-se supor

IterableExtension.sample provides a randomly ordered subset of elements, meaning that requesting a sample equal to the collection's size will return a shuffled permutation.

Contrato

• Before 1.19.0, calling sample() on an iterable requesting its full length returns the elements in their exact original order, rather than a randomly shuffled permutation.
• if ([1, 2, 3, 4, 5].sample(5).toString() != '[1, 2, 3, 4, 5]') throw Exception('Failed');
