that is the point, I don't want to build another DSEL (and wouldn't
know how to do it with proto),
C++ language as a DSEL is enough to experiment with the expressions
right know, and that is the
reason I ended up using phoenix.

well that would be perfect. I don't imagine how (just because I still
don't understand proto)
but in any case I should be able to do it for the current phoenix, ...
in principle.
or I'll rather wait for Phoenix3.

sure. I am surprised that I am using phoenix in a way that was not
intended for. What are expression for if not to take them appart and
analyse piece by piece?
