I mean Javascript does / did the same thing (var loop variables get hoisted to the function scope, so they are available outside of the loop; add to that that `range` creates a pointer and you have a perfect storm of weird, confusing things.

But this is an important point: They were aware of it; it was by design; they had the chance to change it before 1.0 and didn't, and now they are showing willingness to change. So many languages are resistant to change on the one hand (I mean Go is), yet not resistant to keep adding features (e.g. Java / JS).
