I find it easier to think of things visually (I always did well in geometry but stumbled in algebra). What we're really working with is the notion of sets, so I think of a Venn diagram. I picture this:
"x | y"
as "The set of all x-things and the first y-thing."
"(x | y)"
as "The first element of the set of all x-things and all y-things."
Is that about right?
