Lisp-programmer does not count brackets, but visualizes the linked list world in some other way. My world consists of brown and red LEGO-bricks. They are clued together in pairs and brown bricks are things and red bricks abstract links. These greasy fake bricks were only playthings we had in the cheap-ass post-war daycare center 1957. Anyways it would interesting to see 3D-environment where this Lego-paradigm is implemented. I sometimes think about it, but do not find really beautiful way to name things, except tags with letters on them.
