Re^2: How can I stop relying on a global variable?

One thing I failed to mention: The function and the method are in different files. This code comprises a suite of modules working together. When writing modules, I normally don't like putting my methods in the same file as my functions. For example, this one particular method that alters the global hash belongs to a base class. And the function that checks the hash is exported by a module. Both the module and the base class are part of the application.

Sounds like a good place to have a Class::Singleton instance to hold shared configuration information between the different modules. Update: Just to keep this from growing too deep, for more explanations on what a singleton is see the PPR wiki entry for the Singleton pattern.	[reply]

Could you please elaborate? I have heard of "singleton classes" before but I don't know what they are. And how could one help me here?	[reply]
