Background: TypeScript Generics Wishlist

There are a handful of issues that are both separate features, but are also loosely related in that they speak to certain problematic aspects of generics today. In particular,

• [#7061] (specifically later in the thread) asks for a way to assign a private alias to a complex typed derived from the actual type parameters, usable from within the class/function signature.

open.onupgradeneeded = function() {
    var db = open.result;
    var store = db.createObjectStore("MyObjectStore", {keyPath: "id"});
