A nice rename and consistency fix PR for our run conditions. Run conditions can be combined in 0.13 using `and_then` and `or_else`. But there are two problems here: first, why are we using these weird monadic names? Second, why not have the rest of the binary operations?
I spent a while socializing this change: bikeshedding can get intense but everyone thought it was a good idea.
Merging, but not cherrypicking: this is a new feature.
