If you needed to setup an S3 bucket that triggers a Lambda function when an object is added, how would you do that? Last I looked, the S3 resource would get created lazily, the Lambda wouldn't get an S3 ARN, as the S3 bucket didn't exist yet and the stack would fail.

It's a super obvious way to use S3 and Lambda, but the docs recommend something insane.
