nah. reading s-expressions needs some getting used to. you're reading
serialized tree structure there after all.

the "1-" is the name of a function. instead of writing

	(1- x)

you could of couse define a function "subtract-one" that does the same
and then write

	(subtract-one x)

but that's not much more readable. you can of course write

	(- x 1)

and any lisp compiler optimizes it.
