     3As described elsewhere, the LispObject is the base component of which the Lisp world in ABCL has been built. Everything is a LispObject. LispObject has 10 methods which might get called when evaluating that "Lisp object": they're all called ''execute'' and implement the zero - nine argument forms and the array argument form (which allows for non-predetermined numbers of arguments).

     5When an object is evaluated one of the appropriate forms of the ''execute'' method is called. Code deeply nests calls to execute() methods, because the evaluation of a function inherently calls execute() methods to call other functions.

     7This system leads to large stack sizes: Java doesn't allow tail call elimination.
