That kind of rope has been available in python since the 90s, though. You should see some of the programs I wrote back then, when I was still learning.

The fact that a language feature can be used badly in unskilled doesn't count much against it, in my book. If it <i>rewards</i> bad practices, that's a much bigger deal. But a language can only go so far to protect programmers from themselves before it starts to get in the way of legitimate efforts.
