So, further work:
* have 'assert' respected when -O is on
* think up a technique for splicing in 'assert' via rewrite rules (or TH ...) such that the src locations are expanded after the rewrite, and correctly reflect the location of the splice point.
Any ideas?
Overall I like what you've said. But when I read it, I wondered, "Why do I have to fix every function which calls error? Why can't we just fix error?" We discussed this a bit in #haskell and it was pointed out that, that would only give us the line number of where error is defined. Someone mentoined stack traces aren't so great in haskell, but Cale sugested we try to get a "cost-center trace" plus line numbers? Even though __FILE__ and __LINE__ are a bit simplistic in C they are quite handy for things like this. $0.02, Jason
