I think the high-level decision to be made here is whether we want to support "full" diagnostics through the whole compiler pipeline. If yes, then one consequence is that someone will have to modify code like this to use proper location information. We might even have to do that if the answer is "no", if the messages are coming from something that is called by the front end.

I'm not certain that this is the tradeoff I prefer, but I haven't exactly done a survey of what diagnostics are emitted where. My general worry is that these more distant (from the FE) diagnostics will also be the ones where having good location information would be the most useful. Tom
