how about a closure where you want to use a var declared outside of the closure

Well, by definition, a closure does operate on variables outside itself... that's the whole point.

As for a closure that is based on a global variable (lexical or otherwise), I can only ask "Why would you want to do a thing like that?" If the variable is global, it sort of defeats the purpose of wrapping it up in a closure. (Otherwise you would just use local).

So yes, you could do so, but I don't think it qualifies as a Real World Example™ as per the OP. I think anything you could come up with could be wrapped up in a sub and use lexical mys, and I think it would be better that way.
