If __noSuchMethod__ is wrong, what's the point of suggesting a way
to simulate it through proxies?
__noSuchMethod__ isn't the same problem as my concern about
invoke-only traps. In this case, (x = sink.bar).apply(sink) would
still hit the __noSuchMethod__ method.
That's right.
Andrea, please see especially this part of the blog post you cited:
"""
This implementation does not just call the |__noSuchMethod__| hook when
a missing method is invoked, as shown after the |obj.bar()| line above.
It also creates a thunk for any |get| of a property not in the target
object and not in |Object.prototype|:
|js> obj.bar
(function (...args) {
return receiver.__noSuchMethod__(name, args);
})
js> var thunk= obj.bar
js> thunk()
"bar"|
I think this is an improvement on my original
<https://bugzilla.mozilla.org/show_bug.cgi?id=196097> |__noSuchMethod__|
creation all those years ago in SpiderMonkey.
