Or, at least _are_ in the sense of being equivalent under slicing...

Whimsical idea: could we use type lists, so we could instantiate a thread
starter
template with the list of exceptions it should wrap, and get slicing
semantics
into the calling context? All other exceptions would fall through, but then
the user can enumerate the "most possible" exceptions.
