states that "debugging often occupies three-quarters or more of development time". I don't think that is my experience in Haskell... more like 1/4 at most. I was wondering what others felt.
Me either; in fact even 1/4 of the time debugging sounds quite high. When I first started using Haskell, most of my time went to fighting with the typechecker, but once the code checked it almost always Just Worked. This is a pleasant experience. Nowadays, I spend the most time trying to understand the problem, relying on the typechecker to tell me when I've misunderstood something. Optimizing for clarity and figuring out the space behaviour are probably the next most time-consuming activities. --Joe English jenglish@flightlab.com
