+My suggestion meets these guidelines:
+* [ ] This wouldn't be a breaking change in existing TypeScript / JavaScript code
+* [ ] This wouldn't change the runtime behavior of existing JavaScript code
+* [ ] This could be implemented without emitting different JS based on the types of the expressions
+* [ ] This isn't a runtime feature (e.g. new expression-level syntax)
