Comment:
The concensus was that something should be done, although opinions
differed on the finer points (e.g. whether to replace the old
`Control.Exception` or add `Control.NewException`). I have applied more or
less my original patches, although I will be further tweaking them shortly
to incorporate some ideas from the thread (e.g. using `onException` rather
than `catchAny`, and removing the `catchAny` function).
There was also some discussion of the hierarchy, and of the difference
between errors and exceptions. Designing (or evolving) a good hierarchy
remains to be done.
