not necessarily.
[1 2 3] is a vector that is not evaluated. Since there is no overload with
things that are, there's no need for a special mark.
'(1 2 3) is currently a way of say, "don't evaluate this list", but it could
have been:
'(1 2 3) is a list that is not evaluated. No loss of generality. it's a
special type of list. One that's not evaluated. as opposed to a special
indicator to the repl.
