Comment (by simonmar):
Yes you can walk the stack, but the problem is that due to the amount of
code transformation that GHC does, it is almost impossible to relate stack
frames at runtime to the original code. The code that runs bears little
resemblance to the code you wrote in the original program. Case
expressions in the compiled code may or may not correspond to case
expressions or pattern matches in the original code, and GHC doesn't
generally keep track of that information.
