I had forgotten about try...of...catch...end.
When is it appropriate to use try E of H catch ... end
instead of try case E of H end catch ... end?

I think the _intent_ is clear, that in try E ... end
it is *only* E that is protected.

It does make sense, but it would be really nice to see
a couple of examples where try .. of .. catch .. end was
the right thing to do.
