      I want to like #rustlang but the duality of string types bothers me. I also have a hard time getting past no generics in Go. I'm spoiled. :(

      @jxxf What do you mean with “duality of string types”?

      @filcab Rust has both character literals and string literals, and they're different types, but an array of char (UTF-32) != string (UTF-8).

      @filcab IMO it's rarely a good idea to have a distinct char type. I predict massive pain ahead for future interactions with Unicode.

      @jxxf @filcab What would you rather have instead?

      @pcwalton @filcab I would rather not have char at all. The notion of a fixed-length character is an outdated one in a Unicode world (imo).

      @jxxf @filcab Well, sometimes you have to put a Unicode code point in a register :)

          @pcwalton I'm not saying it doesn't have utility (it does, very much so) -- only that I think it confuses things more than it helps IMO.

          @pcwalton It's also a principle of least-surprise thing -- e.g., one may expect that string ⇔ Vec<char> but that would be subtly incorrect.
