(region-beginning) => (10 30 50)
(region-end) => (20 40 60)
Could I, as a programmer, trust that the ordering of those values are
always in sync?
Sure, if you don't change anything between one call and the other.
They would both operate from the same data structure.
Maybe these functions are only helper functions, and when I need the
*real* end of a region, I will ask for it explicitly using the
beginning of the region as argument?
Sorry, I do not understand the issue or the scenario.
