As I said: I'm confused...

> There's just no "warning, the variable WILL stay shared" :-P

There might be no warning, but it's still the same problem.

You proved that from the second run on $var isn't shared anymore.

Just a minor change to your code, and the warning appears:

use strict;
use warnings;

$\ = $/;

tst() for (1..2);

sub tst {
   my $var = 1;
   print \$var, " created";
   sub func
     {
        print \$var;
     }
   func();
}

Looks like you found a case insufficiently covered by warnings!
