Functions with a declared this type should return that type when called with 'new' #8109
Description
Given
interface FooType {
x: number;
}
function Foo(this: FooType, x: number) {
this.x = x;
}
let foo/**/ = new Foo(12);Expected:
foo should be of type FooType
Actual:
foo is of type any.
Note: If you name the interface and the function the same thing, then the type of foo is structurally correct.
