You do realize that the object model is just data bundled with functions, right? If I'm using Erlang I can pass in a map that has something like #{ data => [(data)], methods => [(functions)] }. The object style approach is orthogonal to FP. EDIT: Just to be clear, I don't think this is a good idea. It's usually better to pass in one or more data structures and one or more first class functions separately. I'm just saying that it's not too different.
