   * Go has anonymous functions (`func` w/o name)
 * Slices
   * Use `append` to add to a slice; this creates a new slice, so you have to capture the return value (`s = append(s, 100)`)
+* `math/rand`
+  * `rand.Intn`: random integer between 0 and the specified int
+  * `rand.Float64`: random float between 0.0. and 1.0
