This is an honest question: why would you care about that? What does it matter if someone who doesn't know a language (or isn't bothering to learn it) can read code written in that language?
Python sort of forces that on you up-front.
How? Indentation doesn't really matter and, for example, list comprehensions aren't all that obvious to someone who's never seen them before. I can understand "I think sigils might be confusing", but that's such a superficial aspect of programming I'm inclined to dismiss it as such.
