Ken, 

Are you just saying that for selection sets, AND and OR have the same
precedence, or that there is no (you don't believe in?) Boolean order of
precedence?

IIRC, my Boolean algebra classes taught order of precedence similar to
mathematical algebra ie parentheses, NOT, AND and lastly OR (with a splash
of NAND and NOR, and a pinch of XOR there as well!)
