Thanks .. the thing with ref result is very clever!
Should ref result be return result?
ref might not be necessary fo AA but I'm not sure.
I found this in regards to AAs: https://forum.dlang.org/post/baewchcnyfibkvuiyybj@forum.dlang.org
So it might be more efficient in this case to pass the AA as reference.

It's clear that the function needs to return something, but I was thinking if it would make sense to "document" how one works with the accumulator by indicating it as return instead of ref. I just tried to read through: https://dlang.org/spec/function.html#param-storage, but there is more to it .. like return ref, return ref scope, and what not .. so I am not so sure anymore.
