I believe BrowserUK's point is that if foo is just a global subroutine, there is no difference. On the other hand, suppose you had
package Bar; sub new { ... } sub foo { state $bar; $bar++; return $bar; }
Then later...
$bar1 = Bar->new(); $bar2 = Bar->new(); $bar1->foo(); # returns 1, as you would expect $bar1->foo(); # returns 2, as you would expect $bar2->foo(); # returns 3, possibly unexpected
At least this is my understanding. Is this what you meant, BrowserUK?
