Re: [Haskell-cafe] Indentation Creep

Hi

In particular, I wrote a Trie implementation.

Neat, I often feel I should be using one of those, but never do because Data.Map is just too temptingly close by. A couple of the combinators can be used to simplify some bits:

case v of Nothing -> return True Just _ -> return False

becomes: < isNothing v

if e then writeTVar p Empty else return ()

< when e $ writeTVar p Empty There all so seem to be some other common bits:

case re of False -> writeTVar m Nothing True -> writeTVar p Empty

Perhaps that could become a function? Thanks Neil
