The intended use of the standard library here is for users to import
random to get access to whrandom.  whrandom implements a specific
method for generating random numbers.  It could easily be replaced
with a different, improved module at some time in the future.  If user 
code imports random, it will automatically get the benefit of the new
implementation.
