------- Additional Comments from Darin Adler <darin at apple.com>
+++ JavaScriptCore/kjs/PropertySlot.h	(working copy)

Please take out the forward declaration of the HashEntry struct.

I'd love to see the actual functions (getRightContext) inlined as much as
possible. It seems a shame to pay an extra function call for these little
"trampolines".

+	  void setInput(const UString&);

These look indented wrong. What happened?

+    // FIXME: other than sharing code, there is no reason this get function
can't be simpler.

I think that "other than sharing code" is unnecessarily vague here. You need to
be more specific about what is being shared.

-JSValue* nonCachingStaticFunctionGetter(ExecState* exec, const Identifier&
propertyName, const PropertySlot& slot)

I think you forgot to remove the declaration in the JSDOMBinding.h header.

+    if
(!static_cast<JSDOMWindowBase*>(slot.slotBase())->allowsAccessFrom(exec))
+	 return jsUndefined();
+    return static_cast<JSDOMWindowBase*>(slot.slotBase())->getListener(exec,
mousemoveEvent);

These could all be implemented by a call to a single inline helper instead of
repeating this code over and over again.

+void setJSDOMWindowBaseEvent(ExecState*, JSObject*, JSValue*)
+{
+}

These empty functions probably need a comment to explain why they're here but
empty.

+	 void setListener(JSC::ExecState*, const AtomicString& eventType,
JSC::JSValue* function);
     private:

I'd prefer to always have blank lines before private. I've noticed others
recently deleting them, but I want them visually grouped with whatever comes
after the private, not the things before.

+static JSValue* jsEventTargetNodeOnAbort(ExecState*, const Identifier&, const
PropertySlot&);

You could use JS_EVENT_LISTENER_FOR_EACH_LISTENER to avoid having to write
these all out.

+	     # FIXME: this casts to int to match our previous behavior which
turned 0xFFFFFFFF in -1 for NodeFilter.SHOW_ALL

You probably mean "into" here. Also, is there a cleaner way to handle this?

+	 push(@implContent, "	 { \"$key\", @$specials[$i],
(intptr_t)@$value1[$i], (intptr_t)@$value2[$i] },\n");

C++ casts instead?

What? Why no explanation in the ChangeLog.
