I'd like to note that my post is about randomCover, not

randomSample wrapped as a lazy generator.
To be honest, I think RandomCover is (statistically) unsafe to
use right now, as it takes a copy of the random number
generator it is given _by value_.
If it keeps a copy, how it is passed (value or ref) actually
becomes irrelevant.
This is also a strong argument for the reference semantic PRNG
approach.
