Replying to [comment:1 igloo]:
> Ah, I think we actually want `TopHandler` to also try catching the old
`Exception` type. I'll look into this, although I might leave it until
after the base splitting has happened.
I think we've already lost the game if the old `Exception` type ever gets
thrown - then any library using the new exception mechanism will not
recognize the exceptions. As far as I understand the new mechanism,
implementing the full `Exception` class instance should take care of that
- that's what my proposed patch does.
(Hmm, by that reasoning, the {{{Caster (\e -> e)}}} can be safely removed
from the list of attempted casts in said patch.)
