When you need a function that constantly returns the same result :) That probably doesn't tell you any more than you know already, so I'll give you a real world use. My rnd-utils library has a function generating random strings that match a regular expression. It does this by converting a regex into a sequence of functions, and then concatenating the results into a string. So a regex like "ab[def]" would be converted into two functions: [(constantly "ab") (rnd-choice "def")] This can then be turned into a string using: (apply str (map apply function-sequence)) - James --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
