Second Grant Report: Structured Error Messages
Permanent link
Progress on my grant for error message is slower than expected, as expected :-). Life and work, though rewarding, take their toll. Also many of my original ideas turned out to be not very good, and got shot down by @Larry (with good reason).
However I did get around to lay out some specification for exceptions in S32::Exception
(rendered) - some
basic roles, and the relationships between exception, Failure
(lazy/unthrown exceptions) and backtraces.
More importantly I think I'm at a point where I could start to actually implement some of that stuff, and use that experience to update the specification.
