I often find myself asking for identity of something but identity takes
a single argument! Why not have it take as many as one likes but only
return the identity of the first? I find that very handy...do people agree?
(defn identity
"Returns its argument or its first argument when there are more."
{:added "1.0"
:static true}
([x] x)
([x & more] x))
