I wish it was a real "systems" language as well, i.e. not single-threaded/javascript-mindset one. That's why I hope someday we will have a nice cross-platform framework for Swift.
I whish that too, but I'm not holding my breath since Google needs Dart-to-JavaScript compiler, which will continue limiting features Dart can implement. The only way this can change is, if they move to WASM and drop JavaScript target.
