What is the problem with NOPs?
If there are performance regressions in real code, then that needs to be addressed. 
If only in a few toy examples, then that is (IMO) a price worth paying for predictable debugging and profiling.

Raymond:
   Effectively it does cease to exist. A NOP in the bytecode, except maybe in the tightest of loops, is going to be impossible to detect without inspecting the bytecode.

Serhiy:
   The NOP is outside of the loop, so won't slow down the loop.
