in thread Perl Tk Forgetting a Widget

That would be a good reason. My statement was in reference to the OP's

I want to be able to forget/destroy/delete the widget when I move to a new option in the menu so I can create a fresh one to output text from the next script the user will run. [emphasis added]

If the purpose of destroying or forgetting is to clear the widget, using widget->delete is more efficient.
