Yes and Firebug has to have special code for HTMLCollection because

Storage. Rather than modeling new API on old mistakes, consider

developers will find less
confusing. Pseudo-arrays with "except... this and that" makes APIs
intricate and
puzzling. A simpler and less ambiguous approach would be better in my
opinion.
Is there any type of object that holds a collection that does not use
.length? Seems a bit weird to break consistency here in my opinion.
Consistency is exactly not wanted, because it creates the impression of
an array-like access pattern where there is not one. sessionStorage[2]
is not the third item stored. Actually I don't know what it is, I'm
confused.
There are lots of on-line articles explaining Javascript arrays versus
associative arrays (objects). By having a type which is an associative
array -- Storage -- share a property name with Array just makes matters
worse.
