After reading much of this discussion I am beginning to wonder if I am creating closures?

Your do_something() sub will keep a persistent value for %CFG here.  If
this is intended to be static data, that's not a problem.  I would use
an "our" here instead though for static data.

(I must admit that the concept of closures is -for
some reason- very hard for me to grasp)

You're not the only one.  Closures are my least favorite Perl feature
because they're so easy to use by accident and so hard to fully
understand.

So, let's reverse this.

I have a module that will be used in perl.





What's the best approach?

I want all subs in the module to share the stagte of one variable...in my case @context. I also want any changes to @context to only effect the current user/request under mod_perl.
