(Side note, Go did fix scoping of captured variables in for,range loops, which was a back-incompat change, but they justified it by emperically showing it fixed more bugs than it caused (very reasonable). C# made the same change w/ the same justification earlier, which was inspiration for Go.)

And this issue was known from lisps for 50+ years.. if only we could somehow learn from other languages' mistakes.

		Yeah, it blew my mind when I first learned Go had this problem -- like, people have already tripped over this many times! I was pleasantly surprised to see them fix it though.
