This was just an example. I have a more complex scenario in mind where `dot` doesn’t help.

This is very clever: [Is there something like broadcast\_mapreduce? - #15 by fabiangans](https://discourse.julialang.org/t/is-there-something-like-broadcast-mapreduce/6076/15). Perhaps a solution can come out of the `ArrayReduce` struct suggested there.
