This is a philosophical problem.
What is the difference really between:
1. a prewritten engine, and
2. some hypothetical language
each where you write commander keen with 3k loc.
Where the hypothetical language has all the same stuff as the engine, it's just locked away behind a level of abstraction.
if you could write commander keen in 3k of javascript (with the aid of all the stuff that's in a browser) How is that different from writing 3k of C with nothing but this entire commander keen engine already written and ready to go?

What's are we calling an "advance", exactly?
