Ok, that makes sense. Let's hope we don't have a clash of priorities
though. I, for one, would value elegance of the API over compile time
performance. To me, it's pretty much a given that we can never
equal Lambda nor Phoenix-2's CT performance: there will be a noticeable
CT lag. I wish I am wrong.
