You should ! The guy is funny.
Alternatively you can read a page where I translate every step to PicoLisp:
with live code samples (runnable and tweakable ones).

This little program is just a step in a transformation that exhibits the Y
combinator. «code» is meant to be bound to this code:
'((partial) (list '(n) (list 'if '(=0 n) 1 (list '* 'n (list partial
'(- n 1))))))
so we can replace this last line only with «code» in the program.
