> If you are able (somehow) to encapsulate this state, and save and load it faster than you can regenerate it, that’s a win. You can call it caching or memoisation or “incremental compilation” if you really enjoy that sort of thing, but this is such a basic concept that if you cannot understand it, you are going to have a lot of other problems.

If you're going to be condescending like that, it would be nice if you could provide a concrete example of how to incrementally compile vector<T> in the general case in such a way that it's useful and reasonable to redistribute (that is, not tied to a specific architecture or compiler) instead of just waving your hands.
