  2. …that it can optimize the tail call (and is a compile-time error if it can't). See this comment: https://github.com/rust-lang/rfcs/issues/271#issuecomment-18... Nobody's tried implementing it recently, though.

  6. Not an exact timeline, but it's something that's being actively worked on. There's even an RFC: https://github.com/rust-lang/rfcs/pull/1566
    comment by steveklabnik · 2016-04-15 · in Announcing Rust 1.8
  7. …when/if we will see support for higher-kinded types in Rust? There is the RFC thread on Github ( https://github.com/rust-lang/rfcs/issues/324 ), but I haven't been following the trajectory very closely, and a quick synopsis would be…

  31. I read it the same way. There's an open issue for it: https://github.com/rust-lang/rfcs/issues/372 I think one of the main reasons this isn't done is because of the grammar issue. I dimly remember that one of the goals of Rust was to be…

  44. Redefining well-known terms gives nothing except confusion. And https://github.com/rust-lang/rfcs/pull/243 is another step in this direction (beside "?" idea). If usual errors handling will be called "exceptions", then we will have full…
