What you have explained here clears my understanding.

Actually, I had searched around and found Class::Singleton and had followed the documentation in that to work with the singleton objects. I was deriving from Class::Singleton. What you have explained is perhaps a simpler way of doing it without requiring the inheritance.

Also, it had never occurred to me that I could use modules for some of these instead of Singletons.

For example, if I had a set of utility functions, I created a Singleton class for it where a module perhaps would have been more appropriate.

It works. But perhaps it is not the right way and less efficient. Should I go back to clean this up and convert some of the Singletons to modules?
