Of course they can work with random devices. It looks strange

Question on your terminology here: while saturated makes sense,
is it really your intention to restrict things
One minor nitpick - please avoid calling postblit constructor a
"copy constructor", it tends to mislead developers with C++
origins into expecting copy constructor they are used to - and
disappointment when it proves to not be the case.

Hello,
The problem is that a structure for a random algorithm or a
random variable may holds its own precomputed random state, which
is not correct to copy.

Essentially the sampling algorithm carries out its own little
internal pseudo-random process
