> cloning the entire structure for every applied function sounds like it will be slow? is that not what you will have to do in practice?
In short, no - as an example, when an element is added to an immutable map, a big part of the newly produced map is structurally shared with the old one (check out [0].)
As for the ordering, you could have a list of geometry -> geometry functions. You could then take the initial geometry and apply the list of functions in order, or a permutation of it, or drop some functions, or apply some others multiple times, and so on.
But anyway, it's just an idea - thinking in terms of atomic geometry transformations instead of alternations may or may not be easier in more complex scenarios, I don't know :)

this link looks interesting, thanks.
i basically want the alterations to change the data structure, and i want them to do it according to a particular priority eventually. atm there is no priority ordering.
i can already make (almost) arbitrary functions, but you have to register them ahead of time, and they have to follow a particular pattern: http://inconvergent.net/arbitrary-alterations/. this is so that i can control the order in which they are applied, eventually.
