To the contrary, the recent changes cleared the way for a better
random number generator in the numpy namespace.  With my proposal, I
would predict that rands(n) and rands((n,m)) will be used a lot in
tests and examples while more sophisticated functionality will be
easily discoverable via help(rands).  I can also see some benefit in
having rands(n, bool) that is not available at the moment.
