Thanks to you and awhitworth! Very interesting stuff, kept me reading. (And soon searching to understand some of the ideas. And thinking of Linus's puzzle about `call` being faster than a `push` before a jump. Seems to be one of those cases where higher-level abstractions can be optimized better than lower-level ones. I suppose because lower-level ones are too general-purpose, while higher-level ones are constrained.)
