Right. And you realize that the code that you cite should never be called under normal circumstances.

The circumstances don't matter, the code should not have been pushed to cpan

I tend to be a bit dense at times, but how does your advice about what I "should (or 'should never') do", help solve the problem so that such code would never have needed to have been written in the first place?

It only points out another problem , it doesn't try to solve anything
