Aren't "document.forms[0]" and "document.forms.myform" working?

This is an "implementation detail" of the ECMAScript binding.
In C#, these would obviously be mapped to indexers ("public
HTMLElement this[int index] { get { ... } }" and "public object
this[String name] { get { ... } }"), and there is no equivalent in
Java.
I guess that in Python and Ruby, which share their "dynamic" nature
with ECMAScript, these wouldn't be true properties as well (i.e. '0'
in document.forms would be False, and document.forms["0"] wouldn't be
equivalent to document.forms[0])
