(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. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/393#comment:22> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

So shouldn't the definition proposed by @simonpj include them? Or is there a specific reason not to? In fact, shouldn't the exception thrown by {{{undefined}}} include the file & lineno so that the added definition would then become simply {{{f = undefined}}}, as requested in the original ticket? I have already been at a loss by an error such as {{{*** Exception: Prelude.undefined}}} without any references to where. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/393#comment:20> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
