You are just adding to the maintenance cost of the code.
If something makes it much more difficult to analyze by a human, and doesn't
provide much benefit, don't do it.


Esp. when a large fraction of the time, the compiler with far more cycles to burn,
will be able to make the micro optimization.
And another fraction of the time, the computer running the program will have plenty of cycles.
 (granted, the code is larger, and disk cycles are scarce).
