A Common Lisp-style loop with three clauses - the first one
a for loop, the second one an assignment to a variable, and
the third one an assignment to a variable the result of a for
loop - which makes a collection based on certain aspects as
explicitely extracted - and then it is all sorted according to
a user-defined anonymous function to impose a total order.

Hm ... maybe we can use this piece of code in our next book
aimed at absolute beginners, maybe to replace the initial
"hello world" example?
