Another example would be language keywords (though they pass through ExternalInterface just fine because JavaScript is less strict). <code>myVar.class</code> leads to a compiler error but <code>myVar["class"]</code> doesn't. Imagine if you simply couldn't parse XHTML files with E4X because the <code>class</code> attribute throws errors. The ability to use string access for variable names is an important "feature of the language". That’s why you can put quotes around it.
