That would seem to place significant restrictions on the
ability to define effective random number generators and
related functionality ... ?
Why RNG would be a forward range as opposed to just input range?
To specify : the way I see it you either want PRNG to be a
forward range and that fits with value semantics. Or you want
reference semantics and it naturally becomes input range.
