[ just pushes a mark onto the stack. I guess that procedures that look
back on the stack for the mark might find it useful, like counttomark. 
] looks back for the mark to pop the elements for putting into an array.
All marks are the same, they're usually used as a delimiter for the end
of a list for consumption by something else.
