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.
`fold` requires function to return something (see
[doc](https://dlang.org/phobos/std_algorithm_iteration.html#fold)):
for each element x in range, result = fun(result, x) gets
evaluated.
