Flow's Class<T>

[levenleven]

Class<T>

Given a type T representing instances of a class C, the type Class is the type of the class C

Similar can be achieved in Typescript by typeof Foo but requires Foo to be a value, not a type. So can't be used with generics

Constructor part can be easily described by: type Constructor<T> = new (...args) => T;. This of course won't include any static members and won't verify inheritance (classes in Typescript not treated as nominal)

Maybe it is good enough to include only "constructor part"?

I think what you proposed is good enough.

type Class<T> = new (...args) => T

It works correctly for all Flow use case examples (except nominal part but we don't care about it as TS is structural)
