Good point, there hasn't really been any discussion, but I'll look into it,
I think it should be possible - provided default template arguments on a
forward declaration don't trip up any compilers - I'll experiment and see
what happens. Is it just boost::reg_expression (and typedefs thereof) that
you need?
