You are muddling several different things together there.

Complaining about "globals" and then recommending "our" is contradictory
since "our" is used to declare a global variable.

Recommending "my" along with "using the package name" is bad advice since it
won't work (you would be accessing different variables).

I'll leave the in-depth explaining of the differences between "lexical
variables" and "package globals" to other sources, but those are the two
choices. :)
