The error classes are utterly boring except for the wrinkle that the
predefined subclasses of Error -- EvalError, RangeError, and so on --
all have a [[Class]] that is "Error", not their natural class name.
Anyhow, the draft is enclosed.
Unlike the ES3 spec, I've expanded the subclasses of Error i
Both good points. Thanks.

Geoff,
I hope my answer to your previous post helps you along. Since I had to
write that, though, I should just take the prose and copy it into a
draft proposal and we could zero in on something definite and useful in
short order. Stay tuned.

It depends on whether we care about object identity or not for immutable
objects like Name that don't have special support from the language (eg
in comparison operators). Useful question, though. I will ponder it.

Information/discussion item.
In the drafts for predefined classes I've sent out so far, the
interaction between the intrinsic methods and the prototype methods has
more or less uniformly been specified as the prototype calling the
corresponding intrinsic method on its "this" object, for example:
When we've produced a spec to propose as the normative ES4 standard,
it will be, er, normative ;-). The RI at that point will be
informative, but it will be maintained so future editions can
continue to extract code to include in the spec.

The spec is normative. The RI is informative. (It will presumably
have to commit to some things that the spec need not commit to, even
if its something as relatively trivial as the precise workings of the
random number generator.)

Is the RI informative or normative?
When the spec is actually published, will the written word take
precedence, albeit with code fragments from the RI textually included or
will the RI itself be the ultimate arbiter?

There's an open ticket on it that proposes just that, neither accepted

Did the use of ... in the parameter list (in the tail position only, I
assume) of a function call to 'spread' an array of arguments get
accepted into the language? Is the proper way to trampoline all my
constructor args to my superclass going to be:

Don't you want to be able to express rounding mode? And if so, do you
