Yes, I guess something like that. That was just meant as an example of how existing Python allows you to write loops on one line. It's not a good example for a meaningful comprehension in our alternative made-up Python dialect.

Python already mostly allows you to use parens to override the indentation. They would just need to generalise that a bit. Btw, Haskell already does that:

Officially, Haskell has a syntax with curly braces and semicolons; and they define the indentation based syntax as syntactic sugar that desugars to ; and {}. But almost everyone uses indentation based syntax. The exception are perhaps code generators and when posting on a website that messes with indentation.

(And, because it's Haskell, the {}; syntax is just another layer of syntactic sugar for 'weird-operator'-based based syntax like >>=.)
