Indeed, it's approaching full functionality. For those who may want to
experiment, keep in mind that (1) all typed object support is only
available in Nightly builds and (2) all globals are contained behind a
"TypedObject" meta object (e.g., to create a new struct type, you
write:
var Point = new TypedObject.StructType({x: TypedObject.float32, ...})
Here are the major features that are not yet landed and their status:
1. Reference types (Bug 898359 -- reviewed, landing very soon)
2. Support for unsized typed arrays (Bug 922115 -- implemented, not yet
reviewed)
3. Integrate typed objects and typed arrays (Bug 898356 -- not yet implemented)
Obviously #3 is the big one. I haven't had time to dig into it much
yet, there are a number of minor steps along the way, but I don't see
any fundamental difficulties. There are also various minor deviations
between the spec, the polyfill, and the native SM implementation that
will need to be ironed out.

Dmitry and I were planning on beginning work on the actual spec
language soon. The goal is to advance the typed objects portion of the
spec -- which I believe is fairly separable from the rest -- as
quickly as possible, taking advantage of the new process.
