Looks good, but I miss the index :-(
   p3 = bit(3)

I tried several of these kind of constructs,
but I can't find a way to pass the index of the bit,
all trials gave Python errors.
This is obvious above my level of knowledge.
So if this isn't possible, I just use the 8 copies ;-)

I don't think arrays will help, because most operations will be done on a complete byte.

btw, the first notes about what I'm planning to do, can be seen here:
