  • Add mutex keyword to replace ^ type suffix. This makes it clearer that a mutex cannot be mut, since only one of those keywords is allowed.
  • Remove unlock keyword and replace with lock scope. When you lock a value, you create a new scope lock value { }, inside which the value is mut. The value unlocks when exiting out of the scope, either naturally when the code inside the scope is done running, or by exiting from the scope early with return or throw (which will also exit out of the surrounding function, if any), or with break (optionally with a label if needed).
  • Make Futures scoped. Any Futures not awaited by the end of the scope will be discarded, just like any other variable.
  • Add fut keyword to declare a Future instead of the * sigil.
- Add `mutex` keyword to replace `^` type suffix. This makes it clearer that a mutex cannot be `mut`, since only one of those keywords is allowed. - Remove `unlock` keyword and replace with `lock` scope. When you lock a value, you create a new scope `lock value { }`, inside which the value is `mut`. The value unlocks when exiting out of the scope, either naturally when the code inside the scope is done running, or by exiting from the scope early with `return` or `throw` (which will also exit out of the surrounding function, if any), or with `break` (optionally with a label if needed). - Make Futures scoped. Any Futures not `await`ed by the end of the scope will be discarded, just like any other variable. - Add `fut` keyword to declare a Future instead of the `*` sigil.
