I do hope Python keeps incorporating more of the "good stuff" from functional programming. List/dict/set comprehensions make code better - I can look at something and see very clearly that it's correct. Type hinting is a great compromise between beginner/quick scripting needs and offering a fully-baked type system. Type hints do a lot more than most people expect - you can create useful compound and custom types (like Tuple[Int, Str, Iterable]). If we can get some pattern matching in there I'm not sure what I'd do. Spend less time debugging test failures I guess. Not sure what I'd do with that time. Maybe see my family or learn how to bake pastry. Or finally clean the top of the stove. Or just write more Python in the same amount of time? I don't know. Pattern matching.

Cool library, though.

Python 3 threw away pattern matching in function heads; used to be able to deconstruct tuples. I had just discovered that feature in Python 2 when I realized 2 was about to go EOL, and upon porting my code I discovered the change.

A sad day for this Erlang enthusiast.

Union[Duck, OtherDuck] is another nice trick you can use in case of ducks.
