• Use a meaningful title for the pull request. Include the name of the package modified.
• Test the change in your own code. (Compile and run.)
• Follow the advice from the readme.
• Avoid common mistakes.
• Run npm run lint package-name (or tsc if no tslint.json is present).
• Provide a URL to documentation or source code which provides context for the suggested changes: https://github.com/restify/node-restify/blob/master/lib/response.js
• Increase the version number in the header if appropriate.
• If you are making substantial changes, consider adding a tslint.json containing { "extends": "dtslint/dt.json" }.

Got following error in #22171. Took a look into source code and it seems the headers: any property is wrong and therefore I removed it.

Error in restify

ERROR: 735:5  expect  TypeScript@next compile error: 
Subsequent property declarations must have the same type.  Property 'headers' must be of type '() => any', but here has type 'any'.
