I would not call that "declaring a variable". my $var declares a variable.

our $var; merely instructs perl to allow you to access the global variable $<current_package>::var using the short name. No new variable gets created.

package Foo;

$Foo::var = 1;
print "package var is $Foo::var\n";

{ 
    our $var;
    print "same variable using short name is $var\n";
    
    $var = 2;
    print "using short name changed to $var\n";
    print "package var is now $Foo::var\n";
}

print "I said package var is now $Foo::var\n";

$Foo::var = 3;

print "And now it's $Foo::var\n";

{
    our $var;
    print "still the same variable using short name is $var\n";
}

If it were my instead of <our> not only you would not access the package variable $Foo:var, but you'd also declare two separate variables in those two blocks!
