I've been cautiously optimistic about Rhombus since the initial "Racket 2" controversy. I'd have preferred they went with something more like Wisp or Wraith, but it could be a lot worse.
I am somewhat troubled by tricks that are "too magic", like this example from front page:
class Posn(x, y)
fun flip_all([Posn(x, y), ...]):
[Posn(y, x), ...]
flip_all([Posn(1, 2), Posn(3, 4)])
// ⇒ [Posn(2, 1), Posn(4, 3)]
Why should the later Posns be flipped? That's certainly not what I would expect.
(Then again being too magic is working well for Python, e.g. that a<b<c thing)
