Hello,
(=$) :: Monad m => Enumeratee ao ai m b -> Iteratee ai m b -> Iteratee ao m b enum =$ iter = joinI (enum $$ iter)
($=) :: Monad m => Enumerator ao m (Step ai m b) -> Enumeratee ao ai m b -> Enumerator ai m b ($=) = joinE ----------------------------------------------------------------------
The operators sound good to me. My only request would be to put in a usage example in the documentation. I'd be happy to write one if you'd like. Personally, I think that =$ will *greatly* clean up my code.
I have a tutorial to describe how to use the enumerator library in Japanese. Since it is popular among the Haskell community in Japan, I guess it's worth translating into English. So, I did. http://www.mew.org/~kazu/proj/enumerator/ This tutorial explains how to use (=$) and ($=) as well as other operators(($$), (<==<), (>>=)). Of course, my English is broken. If English native speakers will kindly correct broken grammar, it would be appreciated. I'm reachable by e-mail or twitter (@kazu_yamamoto). --Kazu
