No, unfortunately.
I think Eric said that for C++0x, it would be nice to rewrite a lot of 
things to make them simpler and faster to compile.

I think it would be a useful addition in the current Proto without 
re-writing all of it though.

I suspect however that if you don't rely on the default operator 
overloads and call make_expr yourself, it might work.

Do you have an example of a DSL where that would be useful?
