Not to correct those smarter and more knowledgeable, I'd like to call a
rephrase on that one. =o)
my() makes a variable lexical, meaning it isn't in any package.
packages equate to namespaces, which mean little or nothing to
lexicals, who live and die in terms of scope.
Lexicals, (i.e., my() vars) are in *no* package.
Any variable in a package (that's everything you don't declare with
my()...or maybe our()?) is always global.
Now that I've also misphrased that, would someone help me make it
clear? lol....

current file *scope*, no. Current file *package*, yes.
Though I add the caveat that I've never used requires.
I make everything modules.
