Comment 7 for bug 1328169

Assigning to _ for no reason is way less readable. It's not only confusing ("wait, does it somehow matter if this is assigned to a variable?"), but in my opinion the best way to not hide that a function just performs side-effects and doesn't return anything is to *not* assign it to something.

And aligned = are not PEP 8, so you're not going to get me on that argument.
