I would imagine there are some situation in which bitwise would be optimal... couldn't one then simply comment the code for the next developer whom may have to manage the code?

I wouldn't recommend using bitwise operators in production code they are really hard to understand and debug. I had hard time debugging production code that utilized bitwise operators.

great
