The proposed design has disabled copy ctor and uses opCall()

offers the input range primitives.
Yes the problems are inadvertent copies and a disabled this(this)
would prevent that. RNGs should have unique ownership of their
internal state.
Using InputRanges with phobos is somewhat clumsy. Maybe people
have been burned by those and now generally consider InputRanges
as broken.
Maybe non-copyability needs to become a requirement for
InputRanges.
We should add a reference RNG that transforms any other RNG
into an input range that shares the actual RNG.
We already have refRange for that, no?
Also refCounted(Random(unpredictableSeed)) should work.
