+## Use Cases
+
+<!--
+What do you want to use this for?
+What shortcomings exist with current approaches?
+-->
+
+## Examples
+
+<!-- Show how this would be used and what the behavior would be -->
+
+## Checklist
+
+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. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
+* [ ] This feature would agree with the rest of [TypeScript's Design Goals](https://github.com/Microsoft/TypeScript/wiki/TypeScript-Design-Goals).
