Along these lines: > Putting a number on maintainability is less easy than measuring benchmark performance. Anecdotally, as the person who has worked on both systems, I can report that it’s no contest. The current Racket implementation is fundamentally put together in the wrong way (except for the macro expander), while Racket CS is fundamentally put together in the right way. Time and again, correcting a Racket CS bug or adding a feature has turned out to be easier than expected.
