Oh come now.  Between ghci, hpc, and manual analysis I've never hit a
Haskell error and thrown my hands up, "I can't go any further, I'm at a
complete loss!"  Also it helps that I run into this extremely rarely - I
have a larger habit of hidding black holes :-(

It might interest you to know some people actually use hpc for debugging
with reasonble success - it colors the unevaluated sections and this can
be very helpful in determining where a program stopped and threw an
exception.

If you have your eyes on the future you should see Dana Xu's work on
static contract checking (check out her Cambridge page).

Cheers,
Tom
