Can you give an example of how your data structure changes? Getters and setters are only a problem when they come baked into your datastructure, as the only way to access the contents.
If you require more custom getting/setting logic than the built-in datastructures provide, you can always just write a function that does something more complex, and pass the datastructure in as an argument. Its useful to realize that in datastructures, complexity bubbles up, and thus having simpler components makes your problem go away. If your datastructure contains a bunch of components that themselves have their own setters and getters, your datastructure needs to define yet another pair of setters and getters because you need to abstract away the variations in your components. If the components all all just clojure maps, sets, and vectors, then you don't have this problem of needing to account for all this variation.
