([x] x)
The x outside of the vector brackets is the value being returned.
So if max is called with only a single argument, that is also the
returned value.
All of the function definitions have values outside of the vector
brackets (the vector brackets are what represent a specific definition
of the function).
For example:
([x y] (if (> x y) x y))
So in the vector brackets, you've got x and y, which represent 2
values being passed in. Outside fo the vector brackets you've got a
conditional. if the first argument (x) is greater than the 2nd (y),
return x. otherwise, return y.
(if (> a b) ;; if a > b
a ;; return a
b ;; otherwise, return b
))
