I am not sure, at least in the case of the ancestors and decendents operators we can collect the set of titles, after all the list of titles should be “descreat” and then you can do your conditional tests until the first is found.
- The Kin operator is an even more inclusive solution.
My reply here All I want for Christmas - #16 by TW_Tones touches on this indirectly such as using simple nesting to address this logic. Functions that return a list of titles that we can then operate on, do a form of “flatening”, by turning part of the algorithium into a “flat list” then operate on that list.
Simmilarly if we could parse or walk content and generate sophisticated data structures and then query them it would be quite performant way to handle this.
