I'm not sure any change is needed here. The tutorial should be kept concise, and there is already wording a few paragraphs up saying that the scope belongs to the function, not a try or if block.

I concur with Jelle.

Having already known that scope belong to functions (and maybe classes?), the tutorial seems clear and concise, but if I did come from a other language, I think without an explicit statement there is room for confusion.

I agree that it's best not too make the tutorial too bloated so I have no problems with dropping the example, but I still feel just a brief sentence on, say, an if statement would help quite a bit with hammering the point home.
