This kind of thing is hard to prove or even explain, but I feel that Haskell error messages tend to point me to the cognitive mistakes, the ways I&#39;m thinking wrongly about the problem. Whereas scripting language errors just point me to superficial brain farts. By the time I get Haskell code to compile, I already understand that code an order of magnitude deeper. That makes haskell VALUABLE. (to me)<br>
