    Description

      These functions are all conceptually similar and need to promote argument types to a common type. Right now they all have different type promotion heuristics, and there are a few in-progress PRs to improve type support; once those land, we should also reconcile the type promotion logic they use - presumably, all of them should be able to use the exact same logic in the end.
