Well, from what he wrote, it would appear that a random real is a real
that has a non-zero probability of being a sample from the uniform
distribution (0..1).
Or maybe it is a member of no set with a probability of zero of having
one of its members being a sample from the uniform distribution
(0..1).
Something like that. Deep thinking. Come on, you'll know what a
random real is when somebody shows you one.
