Comment:

 Wow, I've created this ticket 9 years ago and I got used to live without
 this feature, although it should be simple to implement. (I hope my old
 username c_maeder was deleted.)

 To answer your question. Yes, source file and line number should be
 included (indicated by "or whatever")

 Adding source file and line number to the Exception for `undefined` is
 obviously not so easy.
