Subject: [Boost-users] [Proto] Accessing nary_expr tag in transform
From: Joel Falcou (joel.falcou_at_[hidden])

I have a nary_expr grammar rule and in its associated tranform, I want
to retrieves the actual tag.

when< nary_expr<_ , bp::vararg<my_grammar> >
     , some_transform_using_the_tag(bp::_tag)

obviously proto::_tag doesn't exist.
How can I retrieve this information ?
