#### Examples:

Example 1. The `pick` function.

    (pick 1 2 3 4 5)
    ⇒ 3
    (pick 1 2 3 4 5)
    ⇒ 2
    (pick 1 1 1 0 2) ; poor man's weighted selection
    ⇒ 1

Example 2. Random selection using `pick`.

    (define (play-pick len)
      (process repeat len
               for o = (pick 0 0 -24 24)
               for r = (pick .1 .2 .2 .2 .4)
               for k = (between 60 67)
               for a = (pick .25 .25 .24 .5 .5 .75)
               output (new midi :time (now)
                           :duration (* r (pick 1.5 .5))
                           :keynum (+ k o)
                           :amplitude a)
               wait r))

    (events (play-pick 60) "test.mid")
    ⇒ "test.mid"
