I have seen the clojure symbol -> used in many places, but I am unsure as to what this symbol is called and does, or even whether it is part of standard clojure. Could someone explain this to me?

-> uses the result of a function call and send it, in sequence, to the next function call.
So, the easier example would be:
Returns 5, because it sends 2, to the next function call (+ 3)
Building up on this,
Returns -2. We keep the result of the first call, (+ 3) and send it to the second call (- 7).
As noted by @bending, the accepted answer would have been better showing the doto macro.
