I like. :) But in the OP, the difference between "and" and "&", or "or" and "|", is subtle yet absolute. They are completely different operators. The bitwise operators function like the arithmetic operators - evaluate both operands, then do something that combines them into one value. The logical operators, though, are more like the if statement: q = a and b is similar to: if a: q = a else: q = b (Pedants, please note that I said "similar" not "equivalent".) They happen to do similar things, but they're completely different in operation. I do like the humour value from the careful selection of operands though!
