Q: Possible to execute a Query in a transaction

[leozilla]

As the title says.

1. is this already supported by diplomat and I am just to dumb to find it?
2. otherwise would it be possible to implement it without a big re-write of the whole library? if yes then I can provide a PR

[leozilla]

I have created a PR for it: #44

[churcho]

I am really keen on this functionality. Any progress update?

Does this cover it all?
