Right, so here's an action plan for a clueless C-programmer:
- Recompile program in debug mode.
- Start application in debugger.
- See where error happens, check out call-stack, check out local
variables and possibly some heap.
- Fix problem, repeat action plan if needed.
Here's an error the Haskell run-time system might throw:
*** Exception: Prelude.head: empty list
So now what? Action plan = . Perhaps Hat could help here? Or the new
GHCi debugger? As a professional C++ programmer and a free-time fan of
Haskell I'm not sure e.g. Visual Studio and the Haskell debugging tools
I've just mentioned are on the same level of usability.
Be careful with your propaganda before you have the real-world tools to
back it up.
Niels, devil's advocate, never idealistic.
