Hi Allen,
Thanks for taking the time to read and respond. I've read your reply in
detail and I feel like it deserves a point-by-point response, but I think
the following might get us on the same page more quickly.
The important point to consider is that I'm *not* comparing this:
A.)
let Blah = BaseClass <| function() {
}.prototype.{
a() {}
b() {}
}.constructor.{};
to this:
B.)
function Blah()
Blah.prototype = Object.create(BaseClass.prototype);
Blah.prototype.a = function() {};
Blah.prototype.b = function() {};
but rather, to what I currently use, which is this:
C.)
var Blah = new Class({
extends: BaseClass,
new: function() {},
a: function() {},
b: function() {},
// also
static: { staticA: 123 }
});
There's no question that the object literal pattern A is superior to B.
But for me, that's a false comparison. It's got to be better than C (or
another similar class API), or I won't use it.
What if I'd like to use the goodies from A (like private named properties
and super references), but I want the API from C? In my review I try to
make that work, with only limited success. That's what I mean when I say
that these features don't provide a foundation for building higher level
class abstractions.
As far as I can tell, there are two ways out of this dilemma:
1.) Allow the RHS of <| to accept a non-literal value (I noticed this
possibility under the Comments and Rationales section of the proto_operator
strawman). This would allow me to set up the prototype chain (on a cloned
version of the input argument) from *within* my class library, instead of
outside of it.
2.) Add declarative class syntax to the language so that I can ditch the
class library.
I hope that makes sense. Please let me know if something needs to be
clarified.
Oh yeah...

You can definitely school me on languages any time, Allen! I'll have to
research Self. And I'll probably give in on this point ; )
