We did the testing with perl 5.6 several years ago. Another danger of the non-list approach is that the function sees the lexical context of its definition and can accidentaly use something from there, which might also leak.

As of now, perl 5.10.0, Tk 804.028, even this code leaks:

perl -e 'use Tk;use Tk::Button;my $top = new MainWindow;for (1..100) {
  for (1..1000) {
    $top->Button(-text=>"foo")->destroy;
  }
  sleep 1;
}
'
