I have an expression wrapper class tied to a domain and a grammar. 
Everythign works ok except for the fact it seems I can't compute type 
inside the expression class that depends on the expression type itself. 
I end up with tons of incomplete type error in proto/fusion.hpp.

The example is a bit big, i'm still working on a small repro but 
basically, what I do is using the expression framework from ym last mail 
is to have a value_type on expression which represent the value_type of 
the expression element.
