Are file scoped variables in a module duplicated with each class instantiation?

[sln]

I have a large hash that is file scoped, a lexical in the module.
Have to make quite a few instantiations of the class.
Is the file scoped lexical hash duplicated each time?
I wouldn't think so but does anybody know the quick answer?

Thanks!

Not unless you specifically do something which causes it be
duplicated.

No. There is only one hash. Your file gets read and compiled only once.
There is only one lexical variable with the name of your hash. Any
instance of your class calls the methods that are defined in your class
file. Each of those methods will access the same lexical variable for
your hash. There is only one.
