I have packaged the Haskell Mode for Emacs at

into RPMs for Red Hat Linux 7.2 (and similar platforms). Once the
packages are installed, Haskell Mode is automatically enabled when you
start up Emacs. Integration with Hugs is the default, but a quick
Using FiniteMap, I often run into robustness problems. For example,
consider the following program, which illustrates a common problem:
