The individual typed array constructors are supposed to inherit their [[CreateAction]] from %TypedArray% and use the definition provided in http://people.mozilla.org/~jorendorff/es6-draft.html#sec-properties-of-the-%typedarray%-intrinsic-object . I probably need to be more explicit about this in http://people.mozilla.org/~jorendorff/es6-draft.html#sec-properties-of-the-typedarray-constructors allen
