> what you actually meant, which in this case is "Perform this constant time operation". This notion is not expressible in most (or almost all) high-level programming languages. Or, to put it another way: If you wrote C or C++ you never mean to say "perform this guaranteed-constant-time CPU operation" (ignoring asm instructions and hardware-aware builtins).
