I don't understand how you could take issue with my statement if you read the entire short paragraph, including this part:

There are exceptions; closures for example. But you have to be careful whenever a value is passed to a sub via broader scope instead of via parameter list.

How could you possibly name closures as an example of how my assertion is outlandish if I, in the very same paragraph named closures as one exception? I even acknowleged that there are other exceptions too. You did read the entire paragraph right? Or should I have enumerated all exceptions within the same sentence as the assertion?
