Folks, I'm a rank beginner in Haskell, and though Haskell seems like a great language to start using, I've got a serious concern about debugging. In about 15 years of Lisp experience, then 15 years of C++, I've gotten pretty accustomed to the idea of using a debugger with lots of pre- and post-conditions on functions, breakpoints, stack trace, and variable inspection -- even though it gets tricky with delayed evaluation, macros, etc. in Lisp! So I don't understand how serious programmers can work on large projects in Haskell with nothing but compiler type-checking and QuickCheck. Yet they get it done, so I must be missing something. Things like the Haskell version of Eclipse seem to provide nothing but syntax coloring and pass-through to 'make': no break points, stack trace, or variable inspection that I can find. Is there some serious IDE (even "emacs + gdb" is serious enough for me) I'm missing? Do Haskell shops develop their own home-grown tools, or do they do something completely different? -- Ben P.
