You don't need #^ to attach the docstring. In fact your version attaches the docstring to the following list, not to the Var. Another note: for functions with only one argument vector you don't need the enclosing (). (defn init-sheet "Initialise a worksheet with a particular month" [current-month] ...)
;For my own reference--this is an example of a Clojure sequence
comprehension
(for [current-month [months]]
(let [current-sheet (init-sheet current-month)])
)
Yes. for is a list comprehension and not a looping construct. And as others pointed out: for is lazy. When you really need looping for side-effects look for doseq. If you also need the results look for dorun or doall. Sincerely Meikel
