Without decorator too (that was Lukasz’ idea). Why bother with the decorator (*if* we were to go there)?
So that def func(params): pass creates a function object, and def func(params) makes a Callable type object? I'm going to *love* explaining the difference to beginners when they accidently do this and try to call func. Python is not Scratch and is not intended as a teaching language for kids, but some proposals are actively hostile to beginners, and I think this is one. Have we considered how this would effect something as simple as the meaning of keywords? - `class` creates classes, also known as types; - `def` creates functions, and also types, but not types you can use for anything except type-checking. Given that annotations are optional everywhere else, what happens if you leave out the annotations in the type definition? def SomethingFunction(x) Is that the same as Callable[[Any], Any] or Callable[[None], None]? Or are we going to create a rule that annotations are mandatory in some `def`s but optional in others? -- Steve
