This has been a rollercoaster of a thread that I’ve been silently but diligently following from the outset. It has also caused me a rollercoaster of emotions 
I do like multis but admit that I do find them clunky. When it comes to boundaries, I’ve never felt good about where they belong. They are side-effect-free so I want to put them in my schemas (or wherever one would normally store queries or changesets), but then you end up with the ol’ “everything is happening somewhere else” problem.
TL;DR, I think being able to use context functions along with with is great and am now excited at the prospect of this being added to Ecto.
As far as the name goes, including with in the name feels a little clunky to me since you get with twice… though it’s not that big of a deal.
Spitball ideas: begin/1 or commit/1 to line up with other db terminology? Likely not one of those but something along those lines…
