>>> The first example is not “terrible”

There are several examples in the blog, and only one is the first. It does not include the "terrible" descriptor after it. So your comment is kind of odd because it doesn't connect to the article at all.

If you mean the first example that's described as "terrible", that's the second example and it's the one with the leaking loop variable. It kind of is terrible, Python has the same problem (and many others, Python scoping rules are not good). C used to have that problem but they at least had the good sense to fix it.
