Thanks, it really helps. I should update my GHC to the newest version (I use the old 6.4.2 with no break command) Is there any editor/IDE supporting this break command? It should be cooler if we can debug functions just by placing mark in the line. > > Stefan > -- Demi masa.. -- Demi masa.. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
I've only written trivial applications and functions in haskell. But the title of this thread got me thinking. In an imperative language you have clear steps, states, variables to watch, etc. What techniques/strategies might one use for a functional language? --ryan
