A big chunk of that was getting D to catch C++ exceptions. And before I did this 
work, neither GDC nor LDC did, either. It's not a simple matter of just turning 
it on given Dwarf EH.

The point being, a lot of things are not going to happen for D unless I do them. 
Many of these require changing the front end, back end, and the runtime library 
in concert. It's a lot easier to make these work when the person working on it 
understands how all three work.

Once they're done, they provide a good guide on how to get it to work with a 
monumental code base like the gdc and ldc backends are.
