and you're ready to evaluate stuff:
Code that's saved in files can be loaded by something like

To start with, here's a short Clojure program that solves the first problem of

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
