I'm afraid you're talking about procedures returning values rather than functions. If so, then agreed. But 100 (pure) functions might be much easier to understand than a 100-line function with many loops, branches, jumps and complex internal state mutations. Assuming no recursive or mutually-recursive calls, you can convert 100 one-line functions to a flat function (no nesting, no loops) with 100 expressions. Another difference in readability is in order - with 100 functions the order of evaluation does not matter, and with a 100 loc imperative procedure, the order of evaluation does matter and is additional thing to keep in mind.
