[Boost-users] [Proto] Turnign grammar into primitive transform : _default is being naughty with me :(

I'm polisihng some generic recursive descent grammar to evaluate various 
sort of expression
that only differ on how nodes and leaf are treated. I was trying, once 
the grammar was set up using combo of transform
to make a single primitive transform to speed up compile-time. 
Everythign worked until I hit a brick wall while trying to
put the last non-generic part (the call to proto::_default) inside my 
own transform.

Here is link to the working.cpp and not_working.cpp stand alone source 
file for inspection.
test were done on 1.42 release.

The error is :

thanks for any pointer on this issue which, I think, is a stupid mistake 
on my side.
