Why not? Many other languages have closures and even Python has lambdas. Multi-line closures work well for these languages including in map/reduce/etc or comprehensions where applicable. Seems like your preference is overfit to Python’s limitations.
Because you can do it in a function. It's not a limitation when you can do it. Having to define a function that's easier to read, and testable as an independent unit, is not a problem.
