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
