A "sub" question...

| I have seen this lately in my readings:]
sub _dfv_profile {
return {
'required' => [ qw( fname lname ) ]
};
}
Note the leading underscore in the sub name. What does that mean? Is that
like making it "private"?

Yes. But as a convention: that means: you sensible reader, don't you
try to rely on this function outside of this immediate realm of code.
But you can cheat as you like - at your risk.

Okay, that is  and a easy way to "mark" something.
Thanks for the answer.
