`Iterable::combineAll` looks to be the same as `Iterable::fold`  or am I missing something?

It's almost the same. `fold` requires `empty` + `combine` while `combineAll` just takes a `Monoid`.

If Arrow really need all these variants is a different discussion :sweat_smile:

I dug into the source and I think there is a duplicity

<https://github.com/arrow-kt/arrow/blob/main/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/Iterable.kt#L983>
would be the fold I mentioned

<https://github.com/arrow-kt/arrow/blob/main/arrow-libs/core/arrow-core/src/commonMain/kotlin/arrow/core/Iterable.kt#L707>
this  is combine all

There is a slight possibility my brain stubbornly ignores the difference :smile: , but I think they are the same.

You're correct! Those are identical, one of the two should probably be deprecated...
