You've still got the concept of data hiding and an object lifecycle, I think. You're right in functional programming we often operate in quite a similar way to "objects without inheritance" - your module has an internal data structure, creates it at some point, manipulates it through a series of module functions. of course in functional you are usually not usually mutating directly.
