JScript Eval Bug

The eval function in JScript doesn't work according to
spec. Specifically, the function C() on page 73 of the
ECMA-262 spec doesn't return the function object
correctly under IIS 5. Binding the anonymous function to
a variable name and then evaluating that works as a
workaround, e.g.

function C() {
return eval("var x = (function (x) {return x*;}); x");
}

works. However, it should be possible to simply evaluate
a function without binding it to a name using the eval
function, especially since the spec has an explicit
example of this.
