There are ways around this, too - create your own Symbol, keep it
closure-private to the class, so it doesn't escape the class's
methods. Have the constructor take an extra argument that must be
equal to this symbol; if it's
But this is not the core of the problem. The problem is the Proxy
introduced in ES6 enables an object to capture and override almost any
operation on an object. Without operation on object, it becomes very costly
(by using an Array of created objects and compare each of them) to identify

Oops, I forget the WeakSet. So seems my private symbol proposal can work now.
Under very deliberately design, private symbol can be used as private field.

WeakSet();var privateSymbol=Symbol('private', true);var

Couldn't the module tag be restricted to be the last tag inside html?
Then we don't need them to be async to avoid blocking rendering and the
declarative order would more closely match the semantics. Multiple tags
could be loaded in parallel and sequenced on execution.

Yes, if you use weak sets in combination with private symbols you can more or
less emulate weak maps. But why not just use weak maps in that case?

Adding Reflect.{isCallable, isConstructor} looks reasonable to me. If the
spec needs these internally, chances are JS developers will need them at
one point. And as you note, typeof === function is a common work-around
in use today. So +1.

I know it could be a little off topic, but just throwing it out there.

If added, it can help ES engines to write more code in ES instead of native
languages. So +1 as well.
