It looks not easy to change the design, the lambda is not only used for string construction and the way the state is applied (only check the state or change it too) is different. Probably it is possible but with more additional special purpose function parameters that add again complexity. Otherwise the current way looks not difficult, just a function that is called on all ranges or out-of-ranges, like an iteration. It can be possible to make a function that instead of calling lambda returns a list of ranges for the within-range or out-of-range case, and then make an iteration over these lists, but this is really only more code, and the returned lists are used only for these iterations.
