 (*) TARAI-4 is (TAK 4 2 0), where TAK is an interesting function
 defined by Mr. Ikuo Takeuchi.
 (DEFUN TAK (X Y Z)
	(COND ((GREATERP X Y)
	       (TAK (TAK (SUB1 X) Y Z) 
		    (TAK (SUB1 Y) Z X)
		    (TAK (SUB1 Z) X Y) ))
	      (T Y) ))
(**) 5.3 with (1- x) etc [no other declarations, so greaterp is closed comp.]
     4.1 with local function declaration (fast subroutine call)
     times on VAX 11/780 at Berkeley

 I understand that the interlisp times can be much improved by using
igreaterp and such-like, so it is not clear that maclisp is quite so
miraculous.
