TypeScript for factory function
I am looking for a guide on how to create a class declaration in a .d.ts file.
The class has a method that takes a type T and returns an instance of T.

You need something creative and then it floats smoothly:
interface Creator<T> {
new (): T;
}
function factory<T>( arg: Creator<T> ): T {
return new arg();
}
// Usage:
class Foo {
something = 123;
}
var foo = factory( Foo ); // foo:Foo
