Well, you can't modify constants. Your problem isn't any different than:

bless \42, "whatever";
sub foo {$_ [0] += 10} foo 42;
Furthermore, the use of bless \pop, shift; is questionable, as there's no order of evaluation defined for the comma in list context.

    That's what I thought at first glance, but after a moment realized that pop, shift on a 2+ element array is going to get the last and first elements regardless of order of evaluation.

    Nevertheless, it's a bad way to do it, since if the method call is given no parameters, the bless will default to package "main" (with a warning).
