Documented Subclasses
Details
The superclass of all objects in the Blocks World (not including the hand).
Subclasses of basic-block characterize different kinds of objects,
and have different properties.
They all have a name, given as block-name and in the examples from the book, a global variable
of that name is used to refer to them.
Since this chapter is an explanation of CLOS, no specific constructor function is defined, and users may call make-instance
directly.
