Really happy that this feature is finally seeing the light of day. When I switched my code from callbacks to promises in node 10 years ago, it seemed like the most natural thing to add that would finally resolve all the resource management fears that node has had with exceptions and error handling. We implemented a solution in bluebird at the time that used closures (it started with a simple sketch https://promise-nuggets.github.io/21-context-managers-transactions.html https://promise-nuggets.github.io/21-context-managers-transa... and ended up much more elaborate http://bluebirdjs.com/docs/api/promise.using.html http://bluebirdjs.com/docs/api/promise.using.html) but this variant is so much cleaner without all the nesting and I'm glad its finally making its way into the standard.
