I don't feel that it's in more poor form than the solution suggested in the article:

    for i := 0; i < 3; i++ {
      defer func(i int) {
       fmt.Println(i)
      }(i)
    }

This shadows `i` pretty much the same amount as what I wrote. If `i` gets a different name inside the lambda, then it'd also be worse because then you could accidentally use `i` still.

I personally prefer the version presented in the article, but your version has at least one nice feature in that you can cleanly specify at the top of the loop body which variables are being shadowed.
