In some sense, from the reactive programming perspective `1..*` is actually easier than `1..$n`. For the latter’s iterator the answer to “do you have another element” implies a conditional somewhere, whereas for the former’s it’s trivially “yes.” Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>
