From Frederik Eaton, on glasgow-haskell-bugs:
I think it would be a good idea to print instructions for getting more information when a program fails with a pattern match or other error.
it should say
foo: Prelude.undefined For information about the location of this error, recompile with "-prof -auto-all" and run with "+RTS -xc -RTS"
Also, maybe these instructions aren't enough? When I do the above, it just prints
which isn't what I was looking for... Am I forgetting an option or something?
