I knew but I hoped there was some tricks :)
I'll tell you in my poor english :)
Imagine you have 2 or more logical array(8,8) and need to performe a bitor(), bitand(), ecc between all elements of the arrays.
Having 2 or more single 64 bit word can be easily:

ret=bitor(first64bit, second64bit, third64bit, and so on)

whitout loops and faster
