A small quibble: I think your summary of the current story
does not tell the full story.
The current report says "at least 30 bits (one Int's worth)".
I think it would be quite reasonable to interpret that as
meaning one full Int's worth, in which case my proposal is
just a clarification, not a change.
Indeed, thinking back, and having just scoured my old mail archives,
I suspect that was indeed what I originally intended when I proposed
separating out the random number generator interface into a separate
class with a method of type `rng -> (Int, rng)':
