Rust Survey 2021 Results
I'm definitely in the camp that worry about the feature/complexity creep.  I saw it with Haskell.  Haskell 98 is a pretty nice and simple language.  GHC Haskell is a monster.  This matters when you try to read other people code and the overuse of experimental cool new features becomes a major burden for comprehension.Rust is already a very large language and for intrinsic reasons pile on a load more complexity than Haskell (just look at the iterators).I write this as a fan and advocate of Rust.
