Indicate example return values

This commit is based on the possibility that the underlying PRNG
may change. Which means that specifying a seed does not guarantee
the results over time. To guard against churn, we indicate that
the shown return values are possible, but not written in stone.

 By default, the returned functions create shallow copies when shuffling. To override the default `copy` strategy, set the `copy` option.
