GHC already carefully collects up almost all messages in a data type called Message, so they are easy to re-direct. However at the moment they collected as strings (well as Pretty.Doc values actually) so they have lost their structure.
I believe that at one time I had a data type for error messages, but there are so many of them and they change pretty often that it was quite a pain having a centralised data type for this. And at the time there was lots of pain and virtually no gain. Changing this would be tedious but do-able. If anyone wants to undertake it, let us know.
