I was surprised to see so many legacy lambda syntax examples in the documentation. This replaces all of them with the new syntax -- excluding the handful of cases meant to explicitly verify the legacy form is still valid. This also adds a link to the issue in the release notes which documents the change in syntax. Related #664
