I've been doing Haskell for a few months, and I've written some mid-sized programs and many small ones. I've read lots of documentation and many papers, but I'm having difficulty making the jump into some of the advanced concepts I've read about.
How do people build intuitions for things like RankNTypes and arrows?
By being told that using them would solve some problem you're complaining about on #haskell or the mailing lists, you look at examples, read up on them, etc. Short version: don't worry about advanced concepts until you have to. If all else fails, it doesn't hurt to write out the low-level version yourself and then get told in a code review that it would be "easier" or more elegant with an advanced technique. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
