Ah, but that's not "length of the array", it's "number of elements in the form".

IE isn't very descriptive :}

Confusing test/result too ;) That's not "first item called myname", it's
"first form element in the myname form". Reason:
myname[0] and myname.item(0) are the same, they lead to
<object-returned-by-'myname'>::get('0').

Yes, no second form element.

But this doesn't answer the "is this behaviour for forms only, or for all nested elements".
Did you try stuff like <div name='test'><div name='test'></div></div>, to
see if your idea about identically-named nested elements is true?

I think this is really only for forms. The fix would be to add a new value to the ReturnType enum
in KJS::HTMLCollection, named "ReturnForm" (i.e. only return form elements),
and add support for it in HTMLCollection, and use that value in kjs_html.cpp:169 
if element.elementId() == ID_FORM.
