Comment (by igloo):
So if an exception handler (for an asynchronous exception) divides by
zero, that would be an asynchronous exception, right? Is that what we
want?
As an alternative, should we actually be throwing
{{{
data SomeExceptionSync = SomeExceptionSync Bool -- synchronous?
SomeException
}}}
with `catch` etc ignoring the `Bool`, but `bracket` etc handling it
appropriately? This would also mean that tail-calling out of an exception
handler would work.
