Comment 2 for bug 1328169

I would like to nuance the statement about "_" being a variable to be ignored.

In lot of places you also find "_" as the gettext shortcut for i18n of textual content.
So I changed my habits 2 years ago, and now I use two underscores for ignored variables.

And I only use it when I need to unpack a tuple and I don't want all the parts, like the example posted in my previous message.
