so much bit-wise logic operations, plus a function call (&, ==, &&,

and every time you create a BO. This nasty judgement happens.
BO creation again is not a fast path. You are committing to allocate
new memory, which is a few orders of magnitude more costly than the few
instructions needed for those comparisons.
What's wrong with you point here is that
We are not going make it more worse because it is worse.
We would like same any single bit of the performance.
It's about the beauty, and beauty and correctness is every thing.
My implement is good both in the perspective of beauty and in the
perspective of the performance.
BO creation is fast or not is irrelevant to what the point we are discuss.
You are always introduce non-critical factor to disturb the discuss,
leading the people go a wrong direction.
