This one looks a bit cryptic. For example, there are two o notations, both of them denote some kind of composition, but different ))
Also ^f notation is non-standard and a bit misleading.
Finally, you can apply eta conversion here: (fun x => f x) == f

we can't apply eta conversion because we use e inside of (same_loc (lab e) \o lab)ᶠ)

This is Kleisli composition. You can use notation (>=>) if you will import monae.

I remember we were discussing that this is related to "tests" from Kleene Algebras with Tests, but currently we cannot use the notation from relation-algebra. So until I will fix the blocking problem in relation-algebra let's either:
- do not use any notation for this;
- use the same notation as in
relation-algebra, so later we'll be able to migrate smoothly.
I prefer the second solution.

should we close this PR for now? |
Let it be here for a while. We'll return to this. |
