How much of Valhalla is this? 50% of it? 90% of it?

50% maybe.

There are other projects that depend having it in place, SIMD (vectors), reiffed generics, non nullable types.

IMO it's the most important 50%. If this alone is delivered I'd call Valhalla a success.

		Agreed. The other are nice to have.
