But in CPython's case, comparisons are extraordinarily expensive compared to
moving data, and the details matter. Moving objects is just copying
-pointers. Comparisons can be arbitrarily expensive (can invoke arbitary

user-supplied Python code), but even in simple cases (like 3 < 4) _all_
decisions are made at runtime: what's the type of the left comparand? the
type of the right? do they need to be coerced to a common type? where's the
