Since most of the other questions have been answered:
https://bugs.webkit.org/show_bug.cgi?id=46541 covers implementation of
DataView. I will try to take care of this in the next week or two. Let
me know if you need it before I've gotten to it.

Both the setter and getter in the Web IDL are defined as omittable,
which means that in the ECMAScript binding the indexing operator ""
is used for both getting and setting values. Both are fully
implemented in JSC and V8. At the C++ level, the "item" and "set"
methods (see IntegralTypedArrayBase and Float32Array for example) are
used in certain cases to implement the getter and setter.
