Why I'm Productive in Clojure (2013)

Since `>` is a function, you can just read the function doc (you can do this by calling (doc >) in the repl):

    user=> (doc >)
    -------------------------
    clojure.core/>
    ([x] [x y] [x y & more])
      Returns non-nil if nums are in monotonically decreasing order,
      otherwise false.

So (> foo bar boo) essentially checks if bar is between foo and boo.

'nums'? Where did that come from? I assume x and y do not have to be nums?

> and < are for numbers, so yes x and y are nums.

If you instead want to compare or sort other values, Clojure offers other functions for that purpose where you can specify in great detail how things should be compared. If > could operate on strings, for example, what would be the expected result? The shorter the string, the "lesser" the value, or the string that starts with the "lower" letter, etc... it's quite ambiguous. You need more than < or > for that kind of comparison.
