Ah, there you have been! In the early 1950s! Now I understand the "quantum leap". It must be a huge jump to go from "pushing data thru registers" to "pushing data thru virtual registers".
Woohoo! It's back to the future! Or forward into the past. Or something like that.
Anyway, when all's said and done (and Parrot's in a state to be rolled out now for many languages, which is a bizarre thought, though nonetheless true) nobody should care that there's Parrot under the hood of their favorite language. We're the plumbing. All you should ever care about the plumbing is whether it works and whether it fits in with whatever you need to hook up to it. If anything more's required then we've failed at least a little.
