It's quite hacky, but this can be done with CPP and quasiquoting (incidentally, it would be _REALLY_ nice if 'undefined' and 'error' had similar source-location-dependent error messages by default):

#define undefined [underscore|"undefined" at line __LINE__ in __FILE__|] That's nice, I like it. Wanted something like this for a while. I rarely get exceptions in Haskell so that it's not even a bother when I don't know what line number an exception came from, even undefined, but it's nice to have it.
