Right, I'll wait to reply in full until then. I just want to point out
that the spec namespace isn't public.
http://wiki.ecmascript.org/doku.php?id=spec:spec gives me a "permission
denied" page.
Hi,
I've noticed that rounding in the reference implementation is implemented using
IEEE roundTiesToEven, but in browsers .5 values appear to round towards zero.
Although roundTiesToEven is desirable from a computational point of view,
there's likely a significant risk that changing to this method

Hi Brendan,
There are many individual aspects of the the ES4 proposal that I like,
many things I don't. All of which I hope to enumerate for this list
over time. But overall my main distress is still the size of the
language.

The spec: namespace holds old, misleadingly inaccurate (for ES4) docs
based on AS3. Nothing there has been touched in many moons. We made
it inaccessible to avoid repeated confusion, and sure enough, when it
was reopened inadventently again for a few days, almost immediately
there was confu

That would be great.
It is one thing to sigh with despair at other people's tend

Thanks for that. I'll file issues in the bug tracker directly in future.

Function findDuplicate is more like "mark duplicates". The side effect
is that it adds a __marker property to each object. As it stands, this
function can not be called more than once. The second call might be
passed a different array, but containing one of those objects that had
the __marker left
InterType Declarations
InterType Declarations are a useful Iand popular) way of adding
functionality to an object, usually to the prototype of a constructor.
Lets say I have a class Widget that I want to borrow from:
class Widget {
private function Widget(){}
static {
getByNode : funct

It's trivial to implement an efficient Set class even in ES3 (with
certain restrictions on the "type" of the key) - just use objects which
are pretty much specialized hash tables (maps from string t

Given the following definitions:
class C {var p: int};
type S1 = {p: int};
type S2 = {p: int, p2: double};
generic function foo(x);
generic function foo(x: *) 0
generic function foo(x: C) 1
generic function foo(x: S1) 2
generic function foo(x: S2) 3
generic function foo(x: like S1) 4
