Printing response headers via middleware?

[denizdogan]

Is it currently possible to print the "final" response headers using a middleware? I'm doing basically the following, but it looks like the iterator has already been "consumed", so there's no way of finding out what the headers were before they were sent. So only the request headers are actually printed using this code.

export const httpLogging =
  (logger: Logger): Middleware => async (ctx, next) => {
    ctx.request.headers.forEach((value, key) => {
      logger.debug(`<- ${key}: ${value}`);
    });
    await next();
    ctx.response.headers.forEach((value, key) => {
      logger.debug(`-> ${key}: ${value}`);
    });
  };
