Re^7: Unusual variable declaration

[Jenda]

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!
