in thread Unusual variable declaration

The point is that our is not doing the same thing. Not even basically. It might look like it does if you use it once, but as soon as you have several ours for the same variable in separate blocks it's clear our is not doing anything like my.

      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.
