Consider:
(-> foo
(f1 p1 p2 p3)
(f2 p4 p5 p6)
(f3 p7 p8 p9))
vs
(f3 (f2 (f1 foo p1 p2 p3) p4 p5 p6) p7 p8 p9)
(assuming I cut and pasted correctly) and you can see a little better where
this is going, especially if you tried putting real names in there.
Is it imperative? Is it declarative? Who cares?
