Is there a way to make a hash entry go away after leaving the current dynamic scope? Similar to 
    sub func {
        local($foo);
        $foo = "bar";
    }

[download]
where $foo goes back to normal after leaving func(), I'd like to have something like 
    sub func {
        my($self) = @_;

        $self->{foo} = "bar";
    }

[download]
only that $self->{foo} should go back to the original value automatically after func() ends.

Ideas, anyone?
