• Remove the try! macro... it has a better replacement in the form of the question_mark (?) operator.

  • Remove std::sync::mpsc from stdlib, making it available externally... it does not feel general enough.

  • Assigning values to struct bindings should use the equal sign, not the colon:

    // now
    Shoe { size: 10, style: "sneaker" };
    // dream
    Shoe { size = 10, style = "sneaker" };
    

    This would be consistent with the rest of the language.

  • All collections types removed, except these basic ones: Vec, HashMap, and HashSet. Also, they would also be available from top-level (i.e. std::{Vec, HashMap, HashSet}), resulting in std::collections removal.
