Andrei and I believe that directly connecting D to C++ is critical for D's 
future. Catching C++ exceptions is a key component of that. This feature has 
been on the table for a year now, and it has become clear that either I do it or 
it never happens.

(Making it work right requires in depth understanding of the other mechanisms 
for EH that dmd uses, how the global optimizer works, how the code generator 
works, how the dwarf support works, how code is converted from ASTs to the back 
end notation, etc. That pretty much just leaves me.)
