OK. let me correct my original statement from: >> f(g(x)) >> >> requires that g(x) be evaluated, before f() can be evaluated. >> to: f(g(x)) requires that g(x) be evaluated, before f() can be *completely* evaluated. > > I think the important point is that functional describes the result > but does not prescibe how to produce it. Another important point is that in many cases evaluation cannot be *completely* "independent" or "parallel". Thinking of it this way is simply wrong.
