in reply to Re^6: Unusual variable declaration
in thread Unusual variable declaration

package Foo; $Foo::y = 42; sub foo { my $x; our $y; ... } sub bar { my $x; our $y; ... }

Each of the two my $x declares a new variable. Both the our $y instruct the compiler to allow you to temporarily use a short name for the same global variable. They do NOT declare a variable!

    Not a definition.

    You are effectively saying reiterating again and again that my and our have differences and are using my as your personal standard for declaration.

    I'm tired of this.
