Thanks for posting the code. It works on pretty large data sets (for
example, a thousand Strings each) and I have a hunch that if I use
Data.ByteString it would even work fast enough on my quarter meg text
files (split on words, ~40,000 and
it's because you not programmed a lot with type classes. if you
start, you will soon realize that type signatures with classes are
just unreadable. just look at sources of my streams library

= h1 - h2 -

Hi -
Disregarding my last proposal which involved the use of {} in types, I am
wondering if anyone would agree with me that it would be a good idea to use
{} instead of () when writing out the context ie:
foo :: (Num a, Bar a) = a - a
would become:
foo :: {Num a, Bar a} = a - a

You can always load things inside ghci with:
:m
i.e.
Prelude :m List
Prelude List :m Control.Concurrent
Prelude Control.Concurrent :m Control.Concurrent List
Prelude List Control.Concurrent

That looks perfect. Is there any reason that Alex doesn't use this? I
