I have a collection of (potentially infinite) sorted iterators I1, I2, I3, … and a nondecreasing value function sort_by((x1, x2, x3, ...)). I want the sorted cartesian product of these iterators. I’m thinking I can do this with a heap (adding a set may in certain edge cases result in a speedup), bu…
