[Haskell-beginners] Debugging in Haskell

[emacstheviking]

I've used Emacs for 30 years so I guess I am biased!  One of the real plus
points is its auto-indenting, it's great for avoiding problems on that
front IMHO. "Ugly" is subjective I guess... try vim them, YouTube has some
great videos on Vim and Haskell.

The Haskell Live video is good.

All the best,
Sean.
