There's quite a difference between a true global variable (as defined with use vars or our or my at file scope), and something like $Package::variable (which is also global in the sense that it's accessible from outside of the package that defined it).
That's not true. Do not confuse file scoped
variables such as my
can declare with package scoped
ones which is what the vars
pragma declares, which are exactly $Package::variables
