bag intersection definition

The "standard" definition when

{1,1,1} intersect {1,1} = {1,1}

is just plain naive. Given that

intersection = projection * equality selection * cross product

(operator multiplication notation is right-associate)

the definition should be:

{1,1,1} intersect {1,1} = {1,1,1,1,1,1}
