I think you can use WTF::IteratorRange here instead.

Please consider Anders's suggestion.

In cases like this, I prefer "unsigned length = this->length()" or "unsigned length = ElementData::length()". It's bad when one thing becomes two. Taking "length" and renaming it to "count" makes it seem like you've changed it somehow, which can be confusing.

My first idea was to just use the Attribute* as the iterator. But for some reason clang really sucks iterating with pointers :(
