PEP 572: Python assignment expressions has been accepted

Must...have...functional...features.

Python's indentation system was so nice for imperative programs. But it gets in the way when functional features are retrofitted. The "everything must be one big expression" style is a total mismatch to Python. The beauty is gone.

Yet using functional staples like map and reduce is discouraged by GvR himself. I guess it's alright as long as the language can adapt to your needs (even though this might contradict the "one obvious way" idea).

Haskell has a similar indentation system, it fits the language very well.
