A singleton class can be transformed into an uninstantiable
class having only static methods. An uninstantiable class with
only static methods can be transformed into a singleton class.
The two designs are duals: Why should one be deprecated and the
other preferred?
If all-static vs. singleton is the most pressing problem
someone faces, he has an easy life indeed!
