When you gain experience in both C++ and Haskell, the time you spend debugging runtime errors in C++ diminishes somewhat. But the time you spend debugging type errors in Haskell diminishes to almost nil. Experience and practice makes perfect -- debugging a type error becomes easy. Maintaining a large C++ application and changing something is more scary (even for the expert) than changing something in a large Haskell program.
