I've no idea where that comes from.

You said using package :: wouldn't pass review. («I'm familiar with "::" but it wouldn't pass code review») So it means that %:: wouldn't pass review.

Again, I've no idea where that comes from; it wasn't mentioned in my post.

True, but you said :: and aaaa::::::bbbb wouldn't pass review, so I extrapolated that Foo:: wouldn't either.

Why write that?

The comment to which I replied assumed replies to your posts are only for your benefit.

My reply to you had "As mentioned, ...".

And I said that that this is irrelevant. Not everything is about you. You asked how to check if something is legitimate package name, and that was an important part of that.
