 * This example shows Recho is a reactive programming environment. Try to
 * change the value of `t`, click the run button and see how the `scale` block
 * is re-evaluated. Meanwhile, you'll notice that the random numbers and the 
 * maximum value don't change, which means only parts of this program re-run --
 * specifically the definition of the scale value (let t = 1) and other places
 * that reference it (const scale = max * t).
