Ok, I've been oversimplifying by reducing it to the functional aspect of it (granted that might come from Scalaz recollection) but I stand by my opinion that too much functionalism will hurt. But, on the other hand, a balance has to be found if Rust ever want to be widely adopted. Let's be honest 2s here, Rust is already hard enough to learn for the average developer, adding higher order function on top of that will not help adoption. IMHO, right now Rust the just enough amount of complexity to still be interesting to the majority. It really depends on who Rust want to target in the long run.
