The fact that it can be used where other languages would use closures doesn't make them equal, and the language here is pretty definite, you're not using "similar", "like" or "can stand in for"… I can do a tree with an array, that doesn't make them equal. I don't want to sound too harsh, I'm just noting that any blog post that starts out like that is a bit likely to be instantly discarded by some people. And will confuse others later on when they want to learn about closures…
