It sounds as though we're planning on Function<ReturnType, InputType>.

I'd just like to note that this is going to put codebases that are in any stage of migration to JDK types from existing libraries including Guava in a really, really bad position.

Every time I see Function<A, B> for years, I am going to have to check the imports to find out whether that's A->B or B-A.

I'm not saying this consideration should trump all others. Just noting that I see this as a very bad problem for my user base.
