In the absence of decimal, Object.eq is trivial to spec:

1. You can't do that in ES3.1 if Decimal is not in ES3.1. You'd have

Hi all,
The following code produces a first is not a function error:
Array.prototype.first = function()
{ return this.length == 0 ? null : this[0]; }
// no semicolon here
(function() { if ([1,2].first() == 1) alert (OK); }())

Ok.
If `identical` is too long, try `id`? Or, since

Hmm. I thought the motivation for using SML is that it had a definite
formal semantics (for which the last revision was published a decade ago),
Not really; I suppose it's nice to know that the underlying
meta-language is formalized, but this would really only provide
practical utility if we
