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.

This proposal does not statify this guideline:

This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)

To expedite the triage process, we need everyone to follow the issue template and instructions.

When you clicked "Create New Issue", the issue form was pre-populated with a template and some instructions. We need you to read those instructions completely, follow them, and then fill in all the fields in that template.

We are not able to assist with issues that don't follow the template instructions as they represent a significantly larger amount of work compared to issues which are correctly specified. Thank you for understanding.
