Every so often I get the urge to dive into Haskell programming. It doesn’t happen often and the periods in between the dives are long enough that I have to start from the beginning each time because I forgot everything I learned last time. It also never lasts that long either, the urge goes away right about when Monads appear. Maybe this urge is similar to the life cycle of cicadas, so I will call the little projects coming from this current urge “Haskell cicadas”.
