Well, if we permit functional programming languages all the problems concerning imperative control flow magically go away...

  I just used higher order functions to keep the example short, and I'd use them irl to avoid code repetition. The concept still applies without them: while (fTrueForAny(xs)) { } boolean fTrueForAny(List xs) { for (Item x : xs) { if (f(x)) { return true; } } return false; } There isn't anything non-imperative about higher order functions. var externalDataStore = new ExternalDataStore() [1, 2, 3, 4].each(x => externalDataStore.store(x)) externalDataStore.getItems().each(item => print(item)) Plenty of higher order functions, and plenty of non-functional, ordered, stateful, imperative code.
