I think there's a confusion in terms. I'm using class var to mean global to the whole class and each instance of the class. My other routine is an instance_var which declares variables for each instance. For my globals, I'm trying to use the package variables referenced by 'our', that are global to the package. AFAIK, they are globals that come into creation when the package does, and if there is code defining them in the package, with an initializer, it gets executed once when that package loads.
There shouldn't be multiple initializations
As far as how I access them: I call them through method calls, meaning I call them through a blessed pointer which I throw away with the shift; Then I store or/and return the global variable passed in from the 'foreach' in '$_' (e.g. one two three), namely the global package variables byte those names.
Does this clear anything up?
