Description
Feature
A similar feature in typescript
const foo: number = 1
type Foo = typeof foo // type Foo = number
function bar(x: string): void {
}
type Bar = typeof bar // type Bar = (x: string) => void
Pitch
The expected way in future python.
Possible implementation: implement __class_getitem__ for type :
foo: int = 1
Foo = type[foo] # equivalent to Foo = int
def bar(x: string) -> None :
...
Bar = type[bar] # equivalent to Bar = Callable[[str], None]

Clarify the intended behavior for variables and functions under the proposed type[...] syntax; done means the typing semantics and compatibility requirements are agreed well enough to implement and test.
