Provides useful anaphoric and monadic versions of if-else and when, as well as infix operators for the actions to allow things like this:
nice package. Especially awhen :: Monad m => Maybe a -> (a -> m ()) -> m () is something I define in almost every project. Note that the documentation: ========== Chainable anaphoric when. Takes a maybe value. if the value is Just x then execute action x , then return True . otherwise return False . ========== does not match the implementation. And looking at the code, you could, you want, build your more special functions upon your more general ones, e.g.: awhen mb action = aif mb action (return ()) Greetings, Joachim -- Joachim "nomeata" Breitner mail: mail@joachim-breitner.de | ICQ# 74513189 | GPG-Key: 4743206C JID: nomeata@joachim-breitner.de | http://www.joachim-breitner.de/ Debian Developer: nomeata@debian.org
