Statements are MOO constructs that, in contrast to expressions, perform some useful, non-value-producing operation. For example, there are several kinds of statements, called `looping constructs', that repeatedly perform some set of operations. Fortunately, there are many fewer kinds of statements in MOO than there are kinds of expressions.
